The Book of Psalms constitutes a sustained call to proclaim God's praises, a theme rooted in the Hebrew title Tehillim, or Songs of Praise, and embodied most directly in Psalm 145, the sole psalm explicitly titled A Praise. Its superscription employs the singular Tehillah, establishing the psalm as a model for praise whose root Hallel appears in the exclamation Hallelujah, literally urging praise of Jah. This motif of Hallel runs from the opening of Book I through the conclusion of Book V, mounting in intensity until the final psalms consist almost entirely of commands to praise. Verses drawn from across the collection illustrate the development: early psalms affirm that God is worthy to be praised according to His righteousness and that His name deserves praise from sunrise to sunset; later ones declare His greatness unsearchable and extend the summons to every created thing. Praise is defined as the attribution of perfections to God for what He is in His holy, blameless character and for what He does in extending mercy, help, and love without partiality. The Hallel Psalms 113-118 gather these strands into one continuous song of praise whose unifying theme is redemption. Psalm 113 opens with five commands to praise God's name and then depicts His sovereign condescension in lifting the poor and granting the barren a home, foreshadowing the elevation of the redeemed to become children and heirs. Psalm 114 recalls the Exodus as the act that made Israel God's sanctuary and dominion. Psalm 115 contrasts the living God who acts with lifeless idols and summons Israel, the priesthood, and all who fear Him to trust the One who blesses. Psalm 116 celebrates deliverance from death, portraying the acceptance of the cup of salvation that leads through sanctification to the precious death of the saints. Psalm 117 widens the circle, commanding all Gentiles and peoples to laud God because His merciful kindness and enduring truth encompass every nation. Psalm 118 culminates the sequence by celebrating the rejected stone that has become the chief cornerstone, the sacrifice bound to the altar, and the light granted through the Son, thereby revealing that redemption is accomplished by Jesus Christ for all mankind. Thus the proclamation of God's praises is presented not as an occasional act but as the lifelong, all-encompassing response to His redemptive work, extending from creation through Israel's deliverance, the regeneration of the saints, and the ultimate salvation of the nations, so that every breath and every generation may declare His glory forever.
