| Matthew Henry's Concise Commentary 118:22,23, may refer to David's preferment; but principally to Christ. 1. His humiliation; he is the Stone which the builders refused: they would go on in their building without him. This proved the ruin of those who thus made light of him. Rejecters of Christ are rejected of God. 2. His exaltation; he is the chief Cornerstone in the foundation. He is the chief Top-stone, in whom the building is completed, who must, in all things, have the pre-eminence. Christ's name is Wonderful; and the redemption he wrought out is the most amazing of all God's wondrous works. We will rejoice and be glad in the Lord's day; not only that such a day is appointed, but in the occasion of it, Christ's becoming the Head. Sabbath days ought to be rejoicing days, then they are to us as the days of heaven. Let this Saviour be my Saviour, my Ruler. Let my soul prosper and be in health, in that peace and righteousness which his government brings. Let me have victory over the lusts that war against my soul; and let Divine grace subdue my heart. The duty which the Lord has made, brings light with it, true light. The duty this privilege calls for, is here set forth; the sacrifices we are to offer to God in gratitude for redeeming love, are ourselves; not to be slain upon the altar, but living sacrifices, to be bound to the altar; spiritual sacrifices of prayer and praise, in which our hearts must be engaged. The psalmist praises God, and calls upon all about him to give thanks to God for the glad tidings of great joy to all people, that there is a Redeemer, even Christ the Lord. In him the covenant of grace is made sure and everlasting.
Pulpit CommentaryVerse 28. - Thou art my God, and I will praise thee: thou art my God, I will exalt thee. This is the acknowledgment made by each and all, and probably repeated many times, while the sacrifice is being consumed upon the altar.
Gill's Exposition of the Entire BibleThou art my God, and I will praise thee,.... These are the words of David, asserting his interest in God as his covenant God; and which is the great blessing of the covenant, and the greatest happiness of men, and will always continue; and for which there is abundant reason for praise: it is an instance of distinguishing grace, all evidence or everlasting love, and the foundation of all comfort and happiness here and hereafter; thou art my God, one will exalt thee; in my heart, and with my lips; and call upon others to join with me in it, as in Psalm 118:29. The Targum is, "thou art my God, and I will confess before thee; thou art my God, and I will praise thee, said David: Samuel replied, and said, Praise, O ye congregation of Israel;'' who are addressed in the next words.
The Treasury of David28 Thou art my God, and I will praise thee: thou art my God, I will exalt thee. 29 O give thanks unto the Lord; for he is good: for his mercy endureth for ever. Now comes the closing song of the champion, and of each one of his admirers. Psalm 118:28 "Thou art my God, and I will praise thee," my mighty God who hath done this mighty and marvellous thing. Thou shalt be mine, and all the praise my soul is capable of shall be poured forth at thy feet. "Thou art my God, I will exalt thee." Thou hast exalted me, and as far as my praises can do it, I will exalt thy name. Jesus is magnified, and he magnifies the Father according to his prayer, "Father, the hour is come; glorify thy Son, that thy Son also may glorify thee." God hath given us grace and promised us glory, and we are constrained to ascribe all grace to him, and all the glory of it also. The repetition indicates a double determination, and sets forth the firmness of the resolution, the heartiness of the affection, the intensity of the gratitude. Our Lord Jesus himself saith, "I will praise thee"; and well may each one of us, humbly and with confidence in divine grace add, on his own account, the same declaration, "I will praise thee." However others may blaspheme thee, I will exalt thee' however dull and cold I may sometimes feel myself, yet will I rouse up my nature, and determine that as long as I have any being that being shall be spent to thy praise. For ever thou art my God, and for ever I will give thee thanks. Psalm 118:29 "O give thanks unto the Lord; for he is good: for his mercy endureth for ever." The Psalm concludes as it began, making a complete circle of joyful adoration. We can well suppose that the notes at the close of the loud hallelujah were more swift, more sweet, more loud than at the beginning. To the sound of trumpet and harp, Israel, the house of Aaron, and all that feared the Lord, forgetting their distinctions, joined in one common hymn, testifying again to their deep gratitude to the Lord's goodness, and to the mercy which is unto eternity. What better close could there be to this right royal song? The Psalmist would have risen to something higher, so as to end with the climax, but nothing loftier remained. He had reached the height of his grandest argument, and there he paused. The music ceased, the song was suspended, the great hallel was all chanted, and the people went every one to his own home, quietly and happily musing upon the goodness of the Lord, whose mercy fills eternity.
