1 Chronicles 16:37-43

37So he left there before the ark of the covenant of the LORD Asaph and his brethren, to minister before the ark continually, as every day’s work required: 38And Obededom with their brethren, sixty and eight; Obededom also the son of Jeduthun and Hosah to be porters: 39And Zadok the priest, and his brethren the priests, before the tabernacle of the LORD in the high place that was at Gibeon, 40To offer burnt offerings to the LORD upon the altar of the burnt offering continually morning and evening, and to do according to all that is written in the law of the LORD, which he commanded Israel;1 41And with them Heman and Jeduthun, and the rest that were chosen, who were mentioned by name, to give thanks to the LORD, because his mercy endureth for ever; 42And with them Heman and Jeduthun with trumpets and cymbals for those that should sound aloud, and with musical instruments of God. And the sons of Jeduthun were porters.2 43And all the people departed every man to his house: and David returned to bless his house.
