8 Church Fathers comment on this verse

Augustine of Hippo

5th centuryChurch Father

Bless the Lord, my soul. Let each soul, united in Christ, express this proclamation. O Lord my God, You are greatly exalted! Where are You magnified? You have enveloped Yourself in beauty and grace. Acknowledge this so that you may be adorned, that He may cover you. Clad in light as if in a garment. Clothed within His church, which now shines brightly in Him, having once been in darkness, as the apostle states: You were once darkness, but now you are light in the Lord. You stretch out the heavens like a curtain, as easily as one could spread out a simple cloth, revealing the glory of the Scriptures over the world; for the skin signifies mortality, and all the authority of Divine Scripture has been conveyed to us through mortal beings whose glory exceeds their mortal end.

He covers the heights with water. What does He cover? The heavenly realms. What is Heaven? Figuratively speaking, we refer to it as Divine Scriptures. What constitutes the heights of the Divine Scriptures? The commandment of love, the highest of which there is none. But why is love likened to water? Because the love of God has been poured into our hearts through the Holy Spirit given to us. Where does the Spirit resemble water? Jesus proclaimed, “Whoever believes in Me, out of his innermost being will flow rivers of living water.” This is affirmed by the evangelist who continues to say, “But this He spoke of the Spirit, which those believing in Him were to receive.” He goes above the wings of the winds, symbolizing the soul's virtues. What is the virtue of the soul? It is self-love. But how will He overcome this? Because God’s love for us surpasses our love for Him.

He appoints spirits as His angels and makes a fiery flame His ministers; these are spiritual beings who serve Him and convey His gospel. If the preacher does not ignite with passion, how will he inspire those who hear his words? He has established the earth firmly. He founded the Church upon the steadfastness of Christ. What is the firmness of the Church? It is the foundation laid by the Apostle: No one can lay any other foundation than that which is laid, which is Christ Jesus. What assurance does this foundation provide? It shall not be moved forever. He has grounded the earth firmly; in other words, He has set the Church upon the foundation of Christ. The Church may tremble if its foundation shakes; yet when would Christ, whose incarnation was the foundation of all creation, who holds all things in His Majesty, be shaken? Since Christ stands firm, the Church will endure eternally. Where are those who claim the Church has vanished from the world when she remains unassailable?

The abyss envelops her like a garment. Whose garment is this? Could it be God’s? But we have already noted His raiment: clothed in light as in a garment. When we hear of God clad in light, we realize that that light pertains to us. What occurs when we desire it? We are no longer in darkness. Thus, if God is wrapped in light, what then is the abyss that is described as a covering? The great mass of waters is named the abyss, encompassing all moist nature and substance, flowing through seas, rivers, and hidden caverns. Therefore, we understand the earth from which He declared, “He founded the earth.” This is further explained by the assertion: “The abyss is its garment”—the waters serve as the earth’s covering.

The waters stood over the mountains; meaning that the abyss, the garment of the earth, increased to such an extent that it overtook even the mountains. We recall this happening at the time of the flood. The prophet, who sought to prophesy the future rather than recount the past, articulated this to convey that the Church would endure through the flood of persecution. There was a time when the flood of persecutors engulfed God’s Church, obscuring even the mightiest among them. Scattered far and wide, they seemed to disappear. Perhaps it is these very waters that lament, “Save me, O God, for the waters have reached my soul,” especially the turbulent waters that render the sea unfruitful. For wherever sea water inundates the land, it renders it barren. Even beneath the water, mountains lay submerged, as above them rose the tide.

Why did the apostles flee? Because the waters surpassed even the mountains. The might of the waters was overwhelming; but for how long? Hear what follows. From Your rebuke they shall scatter. Indeed, it came to pass; by God’s rebuke, the waters receded; they withdrew from the mountains. Now the mountains themselves, Peter and Paul, are exalted! Those who once suffered oppression are now honored like emperors. For the waters fled from God’s rebuke; the heart of kings lies in the hands of God, who directs it as He pleases. He commanded peace for Christians; the authority of the Apostles has flourished and been uplifted.

The waters fled at Your thunder. Who will not tremble at the sound of God through the apostles, the voice of Scripture, through His clouds? The sea calmed, the waters feared, the mountains were laid bare, and the emperor issued decrees. But who would command if God had not spoken? Because according to His will, their commands were executed. Therefore, no man should attribute anything to himself.

The mountains ascend, and the valleys descend to the place You have appointed for them. He continues to speak of the waters. Let us refrain from perceiving mountains merely as earthly; nor valleys merely as terrestrial. The waves of the sea at times swell as mountains which might cover those lofty peaks of the Apostles. But how long do mountains rise and valleys fall? They stormed, then quieted. When they raged, they were mountains; now pacified, they become valleys for He has established a place for them. There exists a channel, deep within where all pent-up sadness retreated.

They were mountains once, now made into valleys: yet, my brethren, even quietness belongs to the sea. Why do they not rage now? Why are they not wrathful? Why do they refrain from attempting to subdue our land, even to obscure it? Why indeed?

Listen; You have set a boundary that they shall not cross or return to cover the earth. What, then, since the fiercest waves have received their measure, should we not preach these truths boldly? Because they have a prescribed limit; they cannot breach the assurance granted neither should they return to overwhelm the earth. What’s happening in the earth itself? What work is emerging now that the sea has withdrawn? The gentle waves caress the shores; though the Gentiles still murmur around, I hear the sounds of the surf but fear not the flood. What is occurring on the ground? Who sends forth springs in the valleys? You send forth springs into low places—those valleys. Understand this, for hills and mountains stand high while valleys represent the low. Do not diminish the lowly; from there springs flow. You send forth springs into the humble valleys.

Witness the mountains; the apostle labored more than any. A sense of greatness rises, but immediately, for the waters to flow, he humbles himself: But not I, the grace of God working with me. There is no contradiction in mountains also being valleys; they are exalted by their spiritual stature and humble by their spirit. Not I, but the grace of God with me.

What is signified that “in the midst of the mountains the waters shall flow through”? The mountains symbolize the great preachers of the Word, esteemed angels of God in the flesh. They are elevated not by their own strength but by grace; yet they possess a humble essence that drives them to pour forth springs of living water. It is expressed that ‘in the midst of the apostles the proclamation of truth flows.’ What exists within the apostles? It is the common heritage shared, a life-giving source that belongs to all equally, and is not limited to just one or another.

If they are not in the midst, they become private property, flowing only for personal gain. But this is not the Gospel of peace. Therefore, beloved, let what has been conveyed serve this purpose because of the springs: may they flow from you as humble valleys, engaging in communion with all that God has gifted you. Let the waters of God flow abundantly in the open space, without envy, be filled, and flow out in fullness. Let the common waters from God be glorified everywhere, rather than the selfish fables of men.

Therefore, all the beasts of the field shall drink. We witness this in creation, where the wild creatures partake of the streams flowing between the mountains. However, since it has pleased God to conceal wisdom beneath the images of nature, not to withdraw it from the diligent seeker but to close it off from the indifferent, and to reveal it to those who earnestly seek, it pleased God Himself to exhort all through us. Thus, in all the material and visible creation, let us seek the spiritually hidden truths that, once discovered, bring joy. The beasts of the field symbolize the Gentiles, which the Scriptures attest in numerous passages.

These creatures quench their thirst fleetingly; they do not remain; they pass through—much like all teaching that has circulated during this time. Unless your love considers that in the city addressing to you, “Praise the Lord, Jerusalem; praise your God, Zion,” for He has strengthened the bars of your gates; now fortified, the city is secure, where no friend departs nor enemy enters, there we shall read from the sacred Word, or the speech that is declared as relevant, as it is presented now. This teaching is presented now so it may stand firm there; now divided in syllables, so it may be contemplated completely. There will be no absence of the Word of God there, nor of letters, sounds, books, or interpreters. How so? As, “In the beginning was the Word,” for He did not come to abandon us; for He was present in the world, and by Him all things were made. Such is the Word we ought to ponder.

For the God of gods shall be seen in Zion. Yet, when? After our pilgrimage, once the journey concludes; unless after our journey we stand before the Judge, who may send us to imprisonment. However, if upon completion of the journey—this we hope, desire, and pursue—we reach our homeland, then we will witness that which we shall eternally praise, and the one who possesses, along with us who partake, shall never be satisfied; nor shall the one who consumes be filled by what they partake. The contemplation shall be sublime and wondrous.

The wild asses shall quench their thirst. The wild asses represent large untamed creatures. Who does not know that wild asses are referred to as onagras? Thus, they symbolize vast untrained individuals. The Gentiles were without the yoke of the Law; many nations lived by their own customs, walking in arrogance, like untamed beasts of the wilderness. And as every beast, so do the wild asses signify a larger group. Each shall be satisfied by their thirst; the waters flow for them. The small hare drinks nearby; the wild ass quenches its thirst from another source: the hare represents the small and timid, whereas the wild ass the bold and fierce; they each partake, yet according to their need.

This stream flows gently, enough that it quenches the wild ass swiftly, and does not intimidate the timid hare. Whether it be the voice of Cicero or another, some reader’s sounds provoke reflection. The less educated may ponder within themselves; who dares aspire to such? It is the sound of flowing water that perhaps appears muddled, yet flows with force enough that a timid creature avoids it. To whom does the Psalm address, asking, “Is it too much for me?” Indeed, the Psalm presents hidden mysteries, resonating so that even children find joy and the unlettered feel drawn to partake and, becoming filled, break into song.

Athanasius the Great

4th centuryChurch Father

He fashioned the moon over time. He revisits the governance of celestial bodies and proclaims that the moon serves no other purpose than to mark and differentiate months and days. The sun recognizes its setting and follows the command of the Lord.

Jerome of Stridon

4th centuryChurch Father

It is observed that as the moon ascends, the yield of the harvest flourishes, and as it descends, it diminishes. This is reflected in the words of the psalmist: "He made the moon in times." Alternatively, we can view the moon as a symbol of the Church. When the Church flourishes, we thrive alongside her, and when she endures trials and experiences a decline, we too feel her afflictions. "The sun hath learnt his west." If the sun can set, why do we presume ourselves to be eternal? It is indeed remarkable that all the light and glory that brightens the entire earth can vanish in an instant. Let us seek in prayer that the Sun of Truth does not go down upon us.

Theodoret of Cyrus

5th centuryChurch Father

He brought the moon into existence at the appointed time. The prophet, after listing all earthly creations, acknowledging the formation of unseen beings, and describing the creation of the heavens, references the heavenly bodies brought to life on the fourth day. He notes that the moon was designed to instruct humanity in the concept of time, as its phases are instrumental in marking the passage of time, delineating the month by its precise increase and decrease in days. The sun knows its setting. This is not due to having life or reason, but rather because it follows the path set by God. Its presence brings forth day, while its absence ushers in night, maintaining a consistent trajectory and rhythm.

Euthymios Zigabenos

11th centuryCommentator

God fashioned the moon in time, as stated by the psalmist who noted that it serves as a source of light during the night, asserting, "The moon and the stars are in the power of the night" (Psalm 135:9). The sun recognizes when it must set, not as a sentient being, but by adhering to the divine command that ordains its presence during the day and its retreat at night. According to Theodoret, the sun symbolizes the reasonable, as it is aware of God's directive. The term "know" is here adapted to describe the sun's fulfillment of its designated path from east to west. Chrysostom remarks that the moon was created solely for the purpose of marking and differentiating months and days; thus, the phrase "in times" reflects this intent.

Genesis states regarding the celestial bodies: "let them be in signs and in times," where Basil interprets "signs" as indicators of weather patterns, and "times" as markers for the shifting seasons: winter, spring, summer, and autumn. Isychias suggests that the moon represents the Jewish synagogue established before the conclusion of the age of the law and the prophets, while the sun symbolizes Christ, who understood the timing of his suffering. Prior to this moment, He indicated that "the hour had not yet come," and when the time arrived, He declared, "The hour has come for the Son of Man to be glorified."

Hesychius of Jerusalem

5th centuryChurch Father

He refers to the moon as the assembly of the Jewish people, established by the Lord during the era of the law and the prophets, while identifying the sun with Christ. The prophet Malachi also spoke of Him, declaring: ‘for you who reverence My name, the Sun of righteousness and healing shall rise in His beams, and you shall go out and shout like fat calves’ (Malachi 4:2). He was aware of His own end; He understood when He would endure His sufferings, and even before the moment arrived, He proclaimed, ‘My hour is not yet come, that the Son of man should be glorified’ (John 2:4, John 12:23).

Irenaeus (Klementjewsky)

18th centuryCommentator

In this passage, the author illustrates another aspect of God's divine governance, indicating that the Almighty orchestrated the movements of the sun and moon in a harmonious manner. This remarkable synchronization not only preserves order through their respective cycles but also serves as an effective means of marking time. The reference to the moon being created "in times" signifies its role in distinguishing between day and night, as well as indicating special periods, such as holy festivals, marking the passage of months and years while providing various blessings to mankind.

When the author states that "the sun knows its west," he refers not solely to the sun's daily orbit but also to its seasonal journey, which brings forth summer, winter, spring, and autumn. The mention of God's establishment of darkness and night, in which "all the beasts of the oak tree shall pass," reveals that God also cares for predatory animals, designating nighttime as their opportunity to hunt. These creatures, being inherently cautious and fearful of humans, typically remain hidden during daylight, even in the face of hunger, opting instead for the cover of night to venture out.

Moreover, while lions and leopards may sometimes emerge during the day due to their hunger, the author emphasizes the more common occurrence of these animals being active at night. This illustrates God's extraordinary care, allowing dangerous beasts to remain concealed during the day, thereby granting humans safer passage. The occasional boldness of lions and leopards in attacking during daylight hours is attributed to the consequences of Adam's transgression, which resulted in the loss of humanity's dominion over the wild creatures.

When it is mentioned that these beasts seek their sustenance from God, it does not imply that they consciously acknowledge Him as their protector. Rather, it signifies that God miraculously provides for even the most ferocious of animals, as previously stated. It is essential to note that while unthinking creatures may obtain food through theft, this behavior is not permitted for humans endowed with intellect and the ability to work with their hands. Instead, they are called to sustain themselves through honest labor, whether by farming or engaging in commerce. Thus, those who resort to thievery, deception, or robbery disrupt the divine order established by God’s Providence.

Psalter with Commentaries (Cave Monastery in Kiew)

19th centuryCommentator

A Psalm composed under divine inspiration by David, celebrating the splendor and majesty of God, the Creator of all existence, reflecting on His remarkable and unfathomable creation of the universe, the heavens, and all that fills them: the earth and its inhabitants, the sea and its contents; the intricate design, righteousness, flourishing, and beauty of creation, as well as the wise and powerful sustenance provided by our Lord Jesus Christ, who is the image of the invisible God, the firstborn of all creation, through whom all things—both visible and invisible—came into being, and in whom they hold together (Rev. 10:6; Col. 1:16). The soul, inspired from above by God, should express gratitude to Him. The majesty of God is eternal and unending.

The Holy Church reflects Christ, as His presence is honored within it. The garment of the God of Light is the inaccessibly brilliant light. God, in His very nature, is invisible and incomprehensible, residing in unapproachable light (1 Tim. 6:16), and He is enveloped in light as a robe, concealing the fullness of His deity; the Evangelist John refers to Him simply as Light. Heaven is represented in the Holy Scripture, which reveals celestial mysteries through scrolls and parchments. The profound truths in Divine Scripture are veiled by the waters, for it is for the Son to disclose them to those whom He chooses. The cloud raised Christ and led Him to ascend into heaven. The wind signifies the swiftness of the Divine; He is omnipresent and sustains all things. Dusi denotes the natural essence of angels, who are incorporeal. An angel serves as a messenger sent by God. Like fire, angels burn with an intense love for God, and they execute God's will with fervor. The prophet refers to angels and spirits interchangeably, as they are inherently intelligent and immaterial flames. The stability of the earth is its stronghold, enduring solely by the power of God; humanity—formed from the earth—stands firm through the sacredness of baptism and the grace of the Holy Spirit. The abyss encompasses the vastness of waters, which cloaked the earth like a veil during the flood. The mountains symbolize the preaching of the prophet, the apostles, and the fathers of holy traditions; upon them, the strength of many waters is manifested in holy baptism. By the authority of holy baptism, demons flee, and the proclaimers of the Gospel instill fear in all wickedness.
