1 Chronicles 23:30–32

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.

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.

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.

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.

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.
