(23) My lips shall . . .--Rather, my lips shall sing while I play to thee, i.e., a hymn should accompany the harp. There is, therefore, no thought of the union of the bodily and spiritual powers in praise of God, though it is natural the verse should have suggested such an interpretation to the Fathers; and indeed the thought of the poet, if we read the whole psalm, with its retrospect of life, is a wish--

"That mind and soul according well,

May make one music as before,

But vaster."

Verse 23. - My lips shall greatly rejoice when I sing unto thee; and my soul, which thou hast redeemed. Not my mouth only, but my heart and spirit, will "rejoice," or "sing out thy praise" (Cheyne), when the time comes, and my "redemption," or deliverance, has been accomplished.

71:14-24 The psalmist declares that the righteousness of Christ, and the great salvation obtained thereby, shall be the chosen subject of his discourse. Not on a sabbath only, but on every day of the week, of the year, of his life. Not merely at stated returns of solemn devotion, but on every occasion, all the day long. Why will he always dwell on this? Because he knew not the numbers thereof. It is impossible to measure the value or the fulness of these blessings. The righteousness is unspeakable, the salvation everlasting. God will not cast off his grey-headed servants when no longer capable of labouring as they have done. The Lord often strengthens his people in their souls, when nature is sinking into decay. And it is a debt which the old disciples of Christ owe to succeeding generations, to leave behind them a solemn testimony to the advantage of religion, and the truth of God's promises; and especially to the everlasting righteousness of the Redeemer. Assured of deliverance and victory, let us spend our days, while waiting the approach of death, in praising the Holy One of Israel with all our powers. And while speaking of his righteousness, and singing his praises, we shall rise above fears and infirmities, and have earnests of the joys of heaven. The work of redemption ought, above all God's works, to be spoken of by us in our praises. The Lamb that was slain, and has redeemed us to God, is worthy of all blessing and praise.My lips shall greatly rejoice when I sing unto thee,.... Both with vocal and instrumental music; this is praising the Lord with joyful lips, Psalm 63:5;

and my soul, which thou hast redeemed; signifying that it would not be lip labour, or bodily service, only that he should perform; but that his heart would go along with his lips in praise; and that under a sense of redeeming love, than which nothing can more strongly engage in such work, Psalm 103:1. For the redemption of the soul is exceeding precious; being the contrivance of infinite wisdom, the fruit of divine grace, and owing to the blood and sacrifice of Christ.
