Source: Nav
2 Chronicles 8:12–16
At that time Solomon offered burnt offerings to the LORD on the altar of the LORD he had built in front of the portico. / He observed the daily requirement for offerings according to the commandment of Moses for Sabbaths, New Moons, and the three annual appointed feasts—the Feast of Unleavened Bread, the Feast of Weeks, and the Feast of Tabernacles. / In keeping with the ordinances of his father David, Solomon appointed the divisions of the priests over their service, and the Levites for their duties to offer praise and to minister before the priests according to the daily requirement. He also appointed gatekeepers by their divisions at each gate, for this had been the command of David, the man of God.

Prepare yourselves by families in your divisions, according to the instructions written by David king of Israel and Solomon his son.

They performed the service of their God and the service of purification, along with the singers and gatekeepers, as David and his son Solomon had prescribed.
