1 Chronicles 16:37-42

MLV(i) 37 So he left there, before the ark of the covenant of Jehovah, Asaph and his brothers, to minister before the ark continually, as every day's work required, 38 and Obed-edom with their sixty-eight brothers. And Obed-edom the son of Jeduthun and Hosah were to be gatekeepers, 39 and Zadok the priest and his brothers the priests, before the tabernacle of Jehovah in the high place that was at Gibeon, 40 to offer burnt offerings to Jehovah upon the altar of burnt offering continually morning and evening, even according to all that is written in the law of Jehovah, which he commanded to Israel.
41 And with them Heman and Jeduthun and the rest that were chosen, who were mentioned by name, to give thanks to Jehovah because his loving kindness is everlasting. 42 And with them Heman and Jeduthun with trumpets and cymbals for those who should sound-aloud and with instruments for the songs of God and the sons of Jeduthun to be at the gate.
