1 Chronicles 16:39-42

39And Zadok the priest, and his brethren the priests, before the tabernacle of Jehovah in the high place that was at Gibeon,

40to offer up burnt-offerings to Jehovah on the altar of burnt-offering continually, morning and evening, and according to all that is written in the law of Jehovah, which he commanded Israel;

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.
