30 They are to be present every morning to offer thanks and to praise the LORD, and likewise in the evening;

31 and at every sacrifice of burnt offerings to the LORD on sabbaths, new moons, and feast days, in such numbers as are prescribed, they must always be present before the LORD

32 and observe what is prescribed for them concerning the tent of meeting, the sanctuary, and the sons of Aaron, their kinsmen, in the service of the house of the LORD.
