Psalms 71:23

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.
