1 Chronicles 16:37-41

So he left Asaph and his relatives there before the ark of the covenant of the Lord, to minister before the ark continually, as every day’s work required,

and Obed-edom with his sixty-eight relatives; Obed-edom, the son of Jeduthun, and Hosah as gatekeepers.

He left Zadok the priest and his relatives the priests before the tabernacle of the Lord in the high place which was at Gibeon,

to offer burnt offerings to the Lord on the altar of burnt offering continually morning and evening, even according to everything that is written in the Law of the Lord, which He commanded Israel.

With them were Heman and Jeduthun, and the rest who were chosen, who were designated by name, to give thanks to the Lord, because His kindness is everlasting.
