I will also praise thee with the psaltery, even thy truth, O my God: unto thee will I sing with the harp, O thou Holy One of Israel.

For I will also confess to thee thy truth with the instruments of psaltery: O God, I will sing to thee with the harp, thou holy one of Israel.

I will also praise thee with the psaltery, even thy truth, my God; unto thee will I sing psalms with the harp, thou holy One of Israel.

I also thank Thee with a vessel of psaltery, Thy truth, O my God, I sing to Thee with a harp, O Holy One of Israel,

I will give praise to you with instruments of music, O my God, for you are true; I will make songs to you with music, O Holy One of Israel.

I also will give thanks unto Thee with the psaltery, Even unto Thy truth, O my God; I will sing praises unto Thee with the harp, O Thou Holy One of Israel.

I will also, O my God! praise thee. He again breaks forth into thanksgiving; for he was aware that the design of God, in so liberally succouring his servants, is, that his goodness may be celebrated. In speaking of employing the psaltery and the harp in this exercise, he alludes to the generally prevailing custom of that time. To sing the praises of God upon the harp and psaltery unquestionably formed a part of the training of the law, and of the service of God under that dispensation of shadows and figures; but they are not now to be used in public thanksgiving. We are not, indeed, forbidden to use, in private, musical instruments, but they are banished out of the churches by the plain command of the Holy Spirit, when Paul, in 1-Corinthians 14:13, lays it down as an invariable rule, that we must praise God, and pray to him only in a known tongue. By the word truth, the Psalmist means that the hope which he reposed in God was rewarded, when God preserved him in the midst of dangers. The promises of God, and his truth in performing them, are inseparably joined together. Unless we depend upon the word of God, all the benefits which he confers upon us will be unsavoury or tasteless to us; nor will we ever be stirred up either to prayer or thanksgiving, if we are not previously illuminated by the Divine word. So much the more revolting, then, is the folly of that diabolical man, Servetus, who teaches that the rule of praying is perverted, if faith is fixed upon the promises; as if we could have any access into the presence of God, until he first invited us by his own voice to come to him.

I will also praise thee with the psaltery - Margin, as in Hebrew, "with the instrument of psaltery." The Hebrew word is נבל nebel. In Isaiah 5:12 it is rendered "viol." See the notes at that passage. It is rendered "psaltery" in 1-Samuel 10:5; 2-Samuel 6:5; 1-Kings 10:12; and elsewhere. Compare the notes at Psalm 33:2.
Even thy truth - I will make mention of thy truth and faithfulness in my songs of praise; or, I will celebrate these in connection with appropriate music.
Unto thee will I sing with the harp - Hebrew, כנור kinnôr. See the notes at Isaiah 5:12. Compare the notes at Psalm 33:2.
O thou Holy One of Israel - The God of Israel or the Hebrew people; the God regarded by them as most holy, and worshipped by them as their God. This is the first time that this title occurs in the Psalm, but it is common in the prophets, particularly in Isaiah. See Isaiah 1:4; Isaiah 5:19, Isaiah 5:24; Isaiah 10:20; Isaiah 12:6. It occurs also in Psalm 78:41; Psalm 89:18.

I will also praise thee with the psaltery - בכלי נבל bichli nebel, with the instrument nebel. Unto thee will I sing with the harp; בכנור bechinnor, with the kinnor. Both were stringed instruments, and the principal used in the Jewish worship; and with which, or any thing like them, in Divine worship, we, as Christians, have nothing to do.

I will also praise thee with the psaltery, [even] thy (q) truth, O my God: unto thee will I sing with the harp, O thou Holy One of Israel.
(q) He confesses that his long delay was well recompensed, when God performed his promise.

I will also praise thee with the psaltery,.... An instrument of music; See Gill on Psalm 33:2;
even thy truth, O my God; that is, his faithfulness in fulfilling his promises, which is never suffered to fail;
unto thee will I sing with the harp; another instrument of music; and both typical of the spiritual melody in the heart, which believers make in praising the Lord, when they sing the Lamb's new song; see Revelation 14:2;
O thou Holy One of Israel; the God of Israel, that dwells among them, and sanctifies them; and who is essentially and perfectly holy in himself, and in all his ways and works; the remembrance of which occasions praise and thankfulness, Psalm 97:12.

To the occasion of praise he now adds the promise to render it.
will . . . praise--literally, "will thank."
even thy truth--as to Thy truth or faithfulness.
