(7) Sing.--Literally, answer, which some think suggests an antiphonal arrangement. Though the strophic arrangement is only loosely marked, the psalm takes a new departure here, with a fresh invocation to praise, going on to fresh proofs from nature of the Almighty Power.

Verse 7. - Sing unto the Lord with thanksgiving. God is not only to be praised for his greatness (ver. 5), but also to be thanked for his loving-kindness (vers. 2, 3, 8, 9). Sing praise upon the harp unto our God. The glad sound of the harp should accompany his praises.

147:1-11 Praising God is work that is its own wages. It is comely; it becomes us as reasonable creatures, much more as people in covenant with God. He gathers outcast sinners by his grace, and will bring them into his holy habitation. To those whom God heals with the consolations of his Spirit, he speaks peace, assures them their sins are pardoned. And for this, let others praise him also. Man's knowledge is soon ended; but God's knowledge is a dept that can never be fathomed. And while he telleth the number of the stars, he condescends to hear the broken-hearted sinner. While he feeds the young ravens, he will not leave his praying people destitute. Clouds look dull and melancholy, yet without them we could have no rain, therefore no fruit. Thus afflictions look black and unpleasant; but from clouds of affliction come showers that make the soul to yield the peaceable fruits of righteousness. The psalmist delights not in things wherein sinners trust and glory; but a serious and suitable regard to God is, in his sight, of very great price. We are not to be in doubt between hope and fear, but to act under the gracious influences of hope and fear united.Sing unto the Lord with thanksgiving,.... These are the words of the psalmist unto the Israelites, according to Aben Ezra and Kimchi; but may be an exhortation to all men, especially good men; who are capable of observing the following things concerning providential goodness and special grace, on account of which they are called upon to "sing unto the Lord": or to "answer" (q); to sing alternately, or by responses; the word is used for singing, Hosea 2:15; see Exodus 15:21; and intends vocal singing, as the next clause instrumental singing, as Kimchi observes. However, the Lord is the object of it, to whom praise is to be sung for all the great and good things done by him, and that "with thanksgiving" to God for them; which, though a distinct thing from singing, and may be done without it, as in prayer; yet singing ought never to be without that; see Ephesians 5:19;

sing praise upon the harp unto our God; an instrument of music used in the times of the Old Testament; an emblem of the heart, and of making melody in it to the Lord: the hearts of believers are the harps of God, on and with which they sing unto him, when they sing aright, and these are in proper tune.
