1 Chronicles 16:39

37So he left Asaph and his brothers there before the ark of the LORD’s covenant, to minister before the ark continually, as every day’s work required;

38and Obed-Edom with their sixty-eight relatives; Obed-Edom also the son of Jeduthun and Hosah to be doorkeepers;

39and Zadok the priest and his brothers the priests, before the LORD’s tabernacle in the high place that was at Gibeon,

40to offer burnt offerings to the LORD on the altar of burnt offering continually morning and evening, even according to all that is written in the LORD’s law, which he commanded to Israel;

41and with them Heman and Jeduthun and the rest who were chosen, who were mentioned by name, to give thanks to the LORD, because his loving kindness endures forever;
