1 Chronicles 16:41-42

41and with them Heman and Jeduthun, and the rest that were chosen, who were expressed by name, to give thanks to Jehovah, because his loving-kindness [endureth] for ever;

42and with them, [with] Heman and Jeduthun, trumpets and cymbals for those that should sound aloud; and the musical instruments of 1God. And the sons of Jeduthun were at the gate.
