Then on that day David first ordained to give thanks to Yahweh, by the hand of Asaph and his brothers.
Payne agreed with this meaning, rendering the first clause here, "David delivered first this Psalm."[3]  He added that, "The following model song (psalm) that David provided them consists, with slight modifications, of  Psalms 105:1-15;  Psalms 96, and  Psalms 106:1,47,48.  All three Psalms are listed anonymously in the Psalter, but upon the basis of David's use of them here, it would appear that David was indeed the author of all three."[4]
