1 Chronicles 15:19

Now these are those whom David caused to stand over the service of song in the house of Yahweh, after the ark rested there.

All these were under the direction of their father to sing in the house of Yahweh, with cymbals, harps, and lyres, for the service of the house of God. Asaph, Jeduthun, and Heman were under the direction of the king.

And the priests stood at their posts, and the Levites also, with the instruments of music to Yahweh, which King David had made for giving thanks to Yahweh—“for His lovingkindness endures forever”—whenever he gave praise by their hand, while the priests on the other side blew trumpets; and all Israel was standing.
