2 Chronicles 8:12-14

Amplified Bible

¹² Then Solomon offered burnt offerings to the Lord on the altar of the Lord which he had built in front of the porch [of the temple], ¹³ a certain number every day, offering them up as Moses commanded for the Sabbaths, the New Moons, and the three annual feasts—the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Booths (Tabernacles).

¹⁴ Now in accordance with the ordinance of his father David, he appointed the divisions of the priests for their service, and the Levites for their duties of praise and ministering and serving before the priests as every day required, and the gatekeepers by their divisions at every gate; for David the man of God had so commanded.
