1 Chronicles 16:40-42

to offer burnt offerings to the LORD on the altar of burnt offering continually morning and evening, even according to all that is written in the LORD’s law, which he commanded to Israel; and with them Heman and Jeduthun and the rest who were chosen, who were mentioned by name, to give thanks to the LORD, because his loving kindness endures forever; and with them Heman and Jeduthun with trumpets and cymbals for those that should sound aloud, and with instruments for the songs of God, and the sons of Jeduthun to be at the gate.
