1 Chronicles 23:31-32

New Catholic Bible

³¹ They were also to do this whenever burnt offerings were made to the Lord on the Sabbath, on the new moons, and on the appointed feasts, as they had been commanded to do regularly before the Lord, ³² that they were to serve the tent of meeting and be responsible for the sanctuary under the direction of the descendants of Aaron, their brethren, for the service of the temple of the Lord.
