Exodus 29:35-37

Darby Translation

³⁵ And thus shalt thou do to Aaron, and to his sons, according to all that I have commanded thee: seven days shalt thou consecrate them.

³⁶ And thou shalt offer every day a bullock as a sin-offering for atonement; and the altar shalt thou cleanse from sin, by making atonement for it, and shalt anoint it, to hallow it.

³⁷ Seven days shalt thou make atonement for the altar and hallow it; and the altar shall be most holy: whatever toucheth the altar shall be holy.
