1 Chronicles 16:40-42

40They were ordered to sacrifice burnt offerings to the Lord. This happened on the altar of burnt offerings continually, morning and evening, as written in the Lord’s Teachings that he gave Israel.

41With Zadok and his relatives were Heman, Jeduthun, and the rest of the Levites who had been selected, chosen by name, to give thanks to the Lord ⌞by singing,⌟ “His mercy endures forever.”

42Also, Heman and Jeduthun played trumpets, cymbals, and the ⌞other⌟ musical instruments that accompany sacred songs. Jeduthun’s sons were stationed at the gate.
