24 You shall bring them near to Yahweh, and the priests shall cast salt on them, and they shall offer them up for a burnt offering to Yahweh.
25 “Seven days you shall prepare every day a goat for a sin offering. They shall also prepare a young bull, and a ram out of the flock, without defect. 26 Seven days shall they make atonement for the altar and purify it. So shall they consecrate it.
