1 Chronicles 16:37-43

37 So he left there before the ark of the covenant of the LORD Asaph and his brethren to minister before the ark continually, each thing in its day;
38 and Obededom with their brethren, sixty-eight; Obededom also the son of Jeduthun and Hosah to be porters.
39 And Zadok, the priest, and his brethren, the priests, before the tabernacle of the LORD in the high place that was at Gibeon,
40 to offer burnt offerings unto the LORD upon the altar of the burnt offering continually morning and evening, according to all that is written in the law of the LORD, which he commanded Israel;
41 and with them Heman and Jeduthun and the rest that were chosen expressly by name, to give thanks to the LORD, because his mercy is eternal.
42 And with them Heman and Jeduthun with trumpets and cymbals to sound, and with other musical instruments of God. And the sons of Jeduthun were porters.
43 And all the people departed each one to his house; and David returned to bless his house.
