27. Also, according to the last precepts of David, the sons of Levi shall be counted by number from twenty years of age and upward.
28. And they shall be under the hand of the sons of Aaron, in the care of the house of the Lord, in the vestibule, and in the chambers, and in the place of purification, and in the sanctuary, and in all the works of the ministry of the temple of the Lord.
29. But the priests shall be over the bread of the presence, and the sacrifice of fine wheat flour, and the unleavened cakes, and the frying pan, and the roasting, and over every weight and measure.
30. Yet truly, the Levites shall stand to confess and to sing to the Lord, in the morning, and similarly in the evening,
31. as much in the oblation of the holocausts of the Lord, as in the Sabbaths and new moons and other solemnities, according to the number and ceremonies for each and every matter, perpetually before the Lord.
32. And let them keep the observances of the tabernacle of the covenant, and the rituals of the sanctuary, and the observance of the sons of Aaron, their brothers, so that they may minister in the house of the Lord.
