Sing to him, sing praises to him; tell of all his wondrous works!
We have here the thanksgiving psalm which David, by the Spirit, composed, and delivered to the chief musician, to be sung upon occasion of the public entry the ark made into the tent prepared for it. Some think he appointed this hymn to be daily used in the temple service, as duly as the day came; whatever other psalms they sung, they must not omit this.

HIS PSALM OF THANKSGIVING. (1Ch. 16:7-43) Then on that day David delivered first this psalm--Among the other preparations for this solemn inauguration, the royal bard had composed a special hymn for the occasion. Doubtless it had been previously in the hands of Asaph and his assistants, but it was now publicly committed to them as they entered for the first time on the performance of their sacred duties.

Sing unto him, sing psalms unto him, talk ye of all his wondrous works. (e) Who of his wonderful providence has chosen a few of the stock of Abraham to be his children.
