Exodus 29:35-37

“Do everything for the ordination of Aaron and his sons exactly as I’ve commanded you throughout the seven days. Offer a bull as an Absolution-Offering for atonement each day. Offer it on the Altar when you make atonement for it: Anoint and hallow it. Make atonement for the Altar and hallow it for seven days; the Altar will become soaked in holiness—anyone who so much as touches the Altar will become holy.
