1 Chronicles 23:28-32

Duties of the Levites

²⁸The work of the Levites was to assist the priests, the descendants of Aaron, as they served at the house of the Lord. They also took care of the courtyards and side rooms, helped perform the ceremonies of purification, and served in many other ways in the house of God. ²⁹They were in charge of the sacred bread that was set out on the table, the choice flour for the grain offerings, the wafers made without yeast, the cakes cooked in olive oil, and the other mixed breads. They were also responsible to check all the weights and measures. ³⁰And each morning and evening they stood before the Lord to sing songs of thanks and praise to him. ³¹They assisted with the burnt offerings that were presented to the Lord on Sabbath days, at new moon celebrations, and at all the appointed festivals. The required number of Levites served in the Lord’s presence at all times, following all the procedures they had been given.

³²And so, under the supervision of the priests, the Levites watched over the Tabernacle and the Temple and faithfully carried out their duties of service at the house of the Lord.
