2 Chronicles 29:27

And Hezekiah commanded to offer the burnt offering upon the altar. And when the burnt offering began, the song of the Lord began also with the trumpets, and with the instruments ordained by David king of Israel.

Cross-reference

2 Chronicles 23:18 confirms the same Davidic ordinance for burnt offerings and singing, now restored by Hezekiah.

2 Chronicles 7:3 describes similar worship—burnt offering and praise—but at Solomon's temple dedication, not Hezekiah's reform.

2 Chronicles 20:21 also links singing with a pivotal moment—Jehoshaphat's battle—though here it accompanies the burnt offering.

Psalm 137:4 shows exiles unable to sing the Lord's song — contrasting with the joyful temple singing here.
