1 Chronicles 16:7

Then on that day David delivered first this psalm to thank the Lord into the hand of Asaph and his brethren.

Cross-reference

2 Chronicles 29:30 shows later use of David and Asaph's words in worship, directly continuing the tradition begun here.

Nehemiah 12:24 references the 'commandment of David' for giving thanks, echoing the appointment made in this verse.

Psalm 105:1 is the exact opening line of the psalm David appointed in verse 7 — it directly supplies the words of verse 8.
