1 Chronicles 16:37-43

So 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: And Obededom with their brethren, threescore and eight; Obededom also the son of Jeduthun and Hosah {to be} porters: And Zadok the priest, and his brethren the priests, before the tabernacle of the LORD in the high place that {was} at Gibeon, To offer burnt offerings unto 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; {morning...: Heb. in the morning, and in the evening} And with them Heman and Jeduthun, and the rest that were chosen, who were expressed by name, to give thanks to the LORD, because his mercy {endureth} for ever; And with them Heman and Jeduthun with trumpets and cymbals for those that should make a sound, and with musical instruments of God. And the sons of Jeduthun {were} porters. {porters: Heb. for the gate} And all the people departed every man to his house: and David returned to bless his house.
