1 Chronicles 16:37-40

David arranged for Asaph and his fellow Levites to serve regularly before the Ark of the LORD’s Covenant, doing whatever needed to be done each day. This group included Obed-edom (son of Jeduthun), Hosah, and sixty-eight other Levites as gatekeepers. Meanwhile, David stationed Zadok the priest and his fellow priests at the Tabernacle of the LORD at the place of worship in Gibeon, where they continued to minister before the LORD. They sacrificed the regular burnt offerings to the LORD each morning and evening on the altar set aside for that purpose, obeying everything written in the Law of the LORD, as he had commanded Israel.
