27 For by David’s last words the Levites were enlisted from the time they were twenty years old.
28 Their duty is to assist the sons of Aaron in the service of the house of the Lord, having charge of the courts, the chambers, and the preservation of everything holy: they take part in the service of the house of God.
29 They also have charge of the showbread, of the fine flour for the grain offering, of the wafers of unleavened bread, and of the baking and mixing, and of all measures of quantity and size.
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.
