From one Lord’s Day to the next comprises eight days, during which the revelation of the New Covenant is manifest, obscured in the Old Covenant by earthly assurances. Seven and eight together total fifteen. The same numeral applies to the Psalms designated as “steps,” reflecting the number of steps in the temple.
Moreover, the number fifty carries rich significance, derived from seven weeks, plus an additional day, resulting in fifty. Seven times seven equals forty-nine, and adding one yields fifty. This number holds such weight that on the fiftieth day following the Lord’s Resurrection, the Holy Spirit descended upon those who were assembled in Christ. Scripture often associates the Holy Spirit with the number seven, as mentioned in Isaiah and Revelation, highlighting the seven Spirits of God due to the Spirit’s sevenfold activity. This sevenfold action is echoed in Isaiah.
Consequently, this fifty-day period is partitioned by the Lord into forty and ten: on the fortieth day post-resurrection, He ascended to heaven, and ten days later, He sent forth the Holy Spirit. The number forty signifies His temporary stay in this world, which is divided into four parts reflecting both the world and the year, while ten represents a reward for fulfilling the law through good works, symbolizing eternity itself. Therefore, the total of one hundred and fifty represents a threefold aspect, akin to multiplication by the Trinity.
Some suggest that the Psalms are split into five books, guided by the recurring phrase, “Let it be so.” However, in my investigation of this division’s rationale, I found it lacking, as the five sections are not equal in length or psalm count, and notably, the fifth book does not conclude with those same words. Yet, in harmonizing with canonical Scripture that states, “For in the book of Psalms it is written,” we affirm there exists a singular book of Psalms. It may be possible that in Jewish tradition, one book can refer to a collection composed of several, just as many churches form one church, or multiple heavens and lands compose one heaven and earth. Daily, we refer to “the ball of the earth” and “the ball of lands.” Thus, when it is stated, “It is written in the book of Psalms,” while seemingly implying a single book, it might well signify any of these five books collectively.
Regardless of these interpretations, this collection, organized into parts of fifty psalms each, conveys a message of great importance and merit. Intriguingly, the fiftieth part emphasizes repentance, the hundredth highlights mercy and judgment, and the hundred and fiftieth exalts praise for God among His saints. In this progression, we embark on a journey towards eternal bliss, acknowledging our sins through repentance before striving to live righteously, culminating in eternal life. Our ultimate fulfillment is found not in ourselves but rather in Him, known to us through His foreknowledge. We are beckoned by the call to repentance, justified by the assurance of mercy and the contemplation of judgment. The one who has received salvation fears not judgment. In responding to this call, we renounce the devil through repentance, shedding his yoke, and, in receiving mercy, we are healed, free from fear of judgment. In glorification, we transition into eternal life, where we shall forever praise God.
The concluding line of this psalm embodies the essence of eternal life. Praise the Lord among His saints, meaning those whom He has exalted; praise Him within the heavens of His strength. Praise Him for His powerful deeds; or, as seen in other interpretations, praise Him for the might of His works according to the abundance of His greatness. All these saints serve as instruments of His praise, as the apostle affirms, “But we may be in him the righteousness of God.” If these saints represent the righteousness wrought in them, why should they not also manifest the power of Christ that enables their resurrection? In Christ’s resurrection, we witness His ultimate power, for in His Passion, weakness is evident, as the Apostle notes. Indeed, it is aptly said that the firmament of His might signifies that He shall no longer die, for death no longer holds sway over Him.
Furthermore, should we not identify them also as the works of divine power He has achieved within them? They themselves embody the fruits of His might, as pronounced, “We are the righteousness of God in Him.” What could reflect greater strength than His reign for eternity, with all His foes vanquished? Shouldn’t they also be viewed as the multitude of His greatness? This notion rests upon how He has elevated them, indicating countless multitudes. Similarly, righteousness encompasses both the essence of His own righteousness and the righteousness He instills in us. These saints are signified thereby through all instruments of music, for the Psalmist’s opening words, “Praise the Lord in His saints,” are fulfilled through diverse expressions of His faithful.
Praise Him with the sound of a trumpet: asserting the distinct pleasure of their praise. Praise Him on the psalter and harp. The psalter resonates from above, while the harp projects from below, reflecting the Creator of both heaven and earth. As noted earlier, the psalter consists of a board supporting strings that offer the best melodies above, while the harp resonates below. Praise Him with drums and voices. The tambourine resonates when the flesh is transformed, devoid of earthly corruption, as it is crafted from dried and reinforced leather. The choir praises God when the gathered community offers harmonious worship. Praise Him with strings and the organ; while the psalter and harp produce strings, the term organ refers generally to musical instruments, despite its common association with air-filled devices. This complexity highlights a broader array of instruments beyond just those that infuse air, as “organ” may refer generally to any musical apparatus.
When discussing strings and the organ, it appears he is referring to instruments possessing strings. For while the psalter and harp contain strings themselves, distinctions arise since sounds emerge from above and below, suggesting a deeper understanding of these strings. Perhaps the inclusion of the organ signifies that they resonate as one harmonious whole, similar to musical instruments arranged in unity. In this future state, God’s saints will manifest their diverse gifts, remaining in agreement with one another, just as harmonious melodies arise from distinct sounds without conflict.
Praise Him upon the cymbals of resonance; praise Him upon the cymbals of joy. Cymbals create sound through contact, often likened to our lips. It seems more fitting, however, to view the praise rendered upon these cymbals as expressed when mutual honor is given among each other, culminating in glorifying God together. To dismiss the cymbals as lifeless sounds, he adds “on the cymbals of rejoicing,” for true exaltation arises from life itself. Furthermore, musicians discern three types of sounds: vocal, breath, and blow. Voices resonate from the throat, breaths come from whistles or similar instruments, while blows emerge from instruments like the harp. These forms are all incorporated: voices in the choir, breath in the trumpet, and blows in the harp, representing mind, spirit, and body through analogy, not literally.
When he declares, "Praise God in His saints," to whom but themselves is this addressed? And who should offer praise to God if not through themselves? “For you are His saints; you are His strength, as a result of His work in you; you are His power and manifestation of His greatness, crafted and revealed in your being. You embody the trumpet, the psalter, the harp, the drum, the choir, the strings, the organ, and the cymbals of joyful sound, all resonating beautifully in unison. Therefore, let nothing trivial, fleeting, or absurd tarnish this exaltation. And since indulging in the flesh leads to death, let every spirit exalt the Lord.
