1 Chronicles 16:37-42

David left Asaph and his coworkers with the Chest of the Covenant of GOD and in charge of the work of worship; they were responsible for the needs of worship around the clock. He also assigned Obed-Edom and his sixty-eight relatives to help them. Obed-Edom son of Jeduthun and Hosah were in charge of the security guards. The priest Zadok and his family of priests were assigned to the Tent of GOD at the sacred mound at Gibeon to make sure that the services of morning and evening worship were conducted daily, complete with Whole-Burnt-Offerings offered on the Altar of Burnt Offering, as ordered in the Law of GOD, which was the norm for Israel. With them were Heman, Jeduthun, and others specifically named, with the job description: “Give thanks to GOD, for his love never quits!” Heman and Jeduthun were also well equipped with trumpets, cymbals, and other instruments for accompanying sacred songs. The sons of Jeduthun formed the security guard.
