Gregory the Theologian and Athanasius declare that the earth's valleys will be filled with wheat, which is necessary for a time, while the well-tended depths of souls will yield spiritual and everlasting nourishment. Thus, the Gentiles’ souls, which previously produced no fruits, will overflow with spiritual blessings. They will cry out in joy and sing. Consequently, all the inhabitants of Jerusalem shall celebrate with heartfelt gratitude, as they have received liberation and been blessed with abundant goodness and remarkable times, which will cause them to sing praises to their Redeemer and generous benefactor. The conjunction "for" is unnecessary here; it would be better stated that they shall call and sing. This psalm is understood in one historical context, but when viewed from a higher perspective, it serves as a prophecy of the Gospel's proclamation. It can also be related to the only begotten Son. The Lord declares that He has visited the earth, which refers to the entire universe, as the term "earth" represents the nations that dwell therein. As Zechariah foretells, the east will shine upon us from above (Luke 1:78). You have enriched her with the wine of reconciliation, as noted earlier (Ps. 59:5). The gospel message has flourished, enhancing this earth—humanity—with virtues. The river of God signifies our Savior, and the waters symbolize His teachings: for He states that rivers make the city of God glad (Psalm 45:5); from this river, like a stream, the divine Apostles flowed forth to nourish the entire world. You have prepared this nourishing word for the nations; you, Lord, have established it through divine teachings and entrusted these teachings to your Apostles, commissioning them to feed the hungry souls; this reflects how true sustenance is provided, as you have arranged it, and not otherwise. The furrows of this earth represent the depths of human hearts, and David's prayers often reflect the need for these hearts to be watered so that they may generate the brilliance of divine love, becoming gentle and soft, devoid of cruelty. The sprouts of this land symbolize virtues, with their yield being faith. The drops represent teachings, from which divine words flow; or the thoughts derived from sacred scripture, which, like dew, refresh the soul, allowing it to rejoice, flourish, and grow. The summer, or season of goodness, is a splendid time for preaching, with Christ as its crown, since He has adorned and beautified it through His deeds and words. The phrase "you shall bless," indicating praise and glorification, may refer to the Father; for thus the Father honored the Son, saying, "This is my beloved Son" (Matt. 3:17). Regarding the fields, hills, and valleys, we can simply say that the Holy Spirit conveys through these images the presence of Christians in every area: the fields will be occupied by priests and church leaders; the hills will house those who live in solitude and ascetics, while the valleys will welcome those dwelling in caves and dungeons. They will each bring a sense of gratitude and joy to their surroundings. Alternatively, low places can symbolize humble souls who do not harbor pride, while the mountains represent those inflated by vanity who have humbled themselves by embracing divine wisdom; ravines depict those who have fallen into sin's depths. Beautiful desert places signify virtuous souls—those of the Gentiles who are capable of producing fruitfulness. The sheep represent the Apostles, who shepherd and govern the flocks of Christ’s word; they were endowed with the grace of the Holy Spirit at Pentecost, as noted: "Remain in the city of Jerusalem until you are clothed with power from on high" (Luke 24:49). Or the sheep symbolize local bishops, overseers, and priests who, through holy baptism and the grace of priesthood, have donned Christ: "For all of you, he says, have clothed yourselves with Christ" (Galatians 3:27). Moreover, it appears that those Jews freed from Babylon, as referenced in this psalm, did not receive such significant blessings and abundance in the historical sense. Thus, it is most fitting to interpret this psalm as one of profound significance.
