This psalm was probably composed by David, soon after his advancement to, and settlement on his throne, 2 Sam. 8. And contains, (1.) His earnest exhortations to persons of all ranks, offices, and states, to praise the Lord, for his everlasting mercy and kindness, ver. 1-4. (2.) By a recital of the great and gracious things which God had done for him, he encourageth himself and others to trust in God alone, ver. 5-18. (3.) His thanksgivings for God’s advancement of him to the throne, notwithstanding of all opposition as typical of the exaltation of Jesus Christ, ver. 19-23. (4.) His, and the priests’ and people’s triumph, in the expected prosperity of his reign; and of the flourishing of the kingdom of Christ, ver. 24-29.
While I sing, let my soul soar aloft to Jesus and his sure mercies. Let me behold him, who for the suffering of death was made a little lower than the angels, now crowned with glory and honour; having all his enemies put under his feet, but himself invested with all power in heaven and in earth; and furnished with all gifts for men, yea, for the rebellious also, that God the Lord may dwell among them; and, as the God of their salvation, daily load them with benefits. Let me rejoice in his highness, and have myself, and all my services, bound with cords to his altar. And God forbid I should conclude the notes, without entering into the very marrow of the sense. Thou art My God, I’ll thee exalt; My God, I will thee praise.
