1 Chronicles 23:28–32

For their duty was to assist the sons of Aaron for the service of the house of the Lord, having the care of the courts and the chambers, the cleansing of all that is holy, and any work for the service of the house of God. Their duty was also to assist with the showbread, the flour for the grain offering, the wafers of unleavened bread, the baked offering, the offering mixed with oil, and all measures of quantity or size. And they were to stand every morning, thanking and praising the Lord, and likewise at evening, and whenever burnt offerings were offered to the Lord on Sabbaths, new moons, and feast days, according to the number required of them, regularly before the Lord. Thus they were to keep charge of the tent of meeting and the sanctuary, and to attend the sons of Aaron, their brothers, for the service of the house of the Lord.

The duty of the Levites was to help Aaron’s descendants in the service of the temple of the Lord: to be in charge of the courtyards, the side rooms, the purification of all sacred things and the performance of other duties at the house of God. They were in charge of the bread set out on the table, the special flour for the grain offerings, the thin loaves made without yeast, the baking and the mixing, and all measurements of quantity and size. They were also to stand every morning to thank and praise the Lord. They were to do the same in the evening and whenever burnt offerings were presented to the Lord on the Sabbaths, at the New Moon feasts and at the appointed festivals. They were to serve before the Lord regularly in the proper number and in the way prescribed for them.

And so the Levites carried out their responsibilities for the tent of meeting, for the Holy Place and, under their relatives the descendants of Aaron, for the service of the temple of the Lord.

“but their duty will be to assist the descendants of Aaron with the service of the Lord’s temple, being responsible for the courts and the chambers, the purification of all the holy things, and the work of the service of God’s temple—as well as the rows of the Bread of the Presence, the fine flour for the grain offering, the wafers of unleavened bread, the baking, the mixing, and all measurements of volume and length. They are also to stand every morning to give thanks and praise to the Lord, and likewise in the evening. Whenever burnt offerings are offered to the Lord on the Sabbaths, New Moons, and appointed festivals, they are to offer them regularly in the Lord’s presence according to the number prescribed for them. They are to carry out their responsibilities for the tent of meeting, for the holy place, and for their relatives, the descendants of Aaron, in the service of the Lord’s temple.”

The 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. They 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. And each morning and evening they stood before the Lord to sing songs of thanks and praise to him. They 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.

And 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.

For their station was to assist the sons of Aaron with the service of the house of Yahweh, over the courtyards, over the chambers, and over the cleansing of all the sanctified objects, and with the work of the service of the house of God, and with the rows of bread, the flour, the grain offering, the wafers of unleavened bread, the baked offering, the offering mixed with oil, and for all the amounts and measurements. And they were to stand every morning, thanking and praising Yahweh, and likewise in the evening, and for every burnt offering offered to Yahweh, on Sabbaths, on new moon festivals, and at the appointed feasts, according to the customary number required of them, regularly before Yahweh. And they shall keep the responsibility of the tent of assembly, the responsibility of the sanctified objects, and the responsibility of the sons of Aaron, their brothers, to serve the house of Yahweh.

Because their office was to wait on the sons of Aaron for the service of the house of the Lord, in the courts, and in the chambers, and in the purifying of all holy things, and the work of the service of the house of God; Both for the shewbread, and for the fine flour for meat offering, and for the unleavened cakes, and for that which is baked in the pan, and for that which is fried, and for all manner of measure and size; And to stand every morning to thank and praise the Lord, and likewise at even; And to offer all burnt sacrifices unto the Lord in the sabbaths, in the new moons, and on the set feasts, by number, according to the order commanded unto them, continually before the Lord: And that they should keep the charge of the tabernacle of the congregation, and the charge of the holy place, and the charge of the sons of Aaron their brethren, in the service of the house of the Lord.
