³⁵ “You must do all these things for Aaron and his sons. You must do them exactly as I told you. The ceremony for appointing them to be priests must continue for seven days. ³⁶ You must kill one bull every day for seven days. This will be an offering for the sins of Aaron and his sons. You will use these sacrifices to make the altar pure, and pour olive oil on the altar to make it holy. ³⁷ You will make the altar pure and holy for seven days. At that time the altar will be most holy. Anything that touches the altar will also be holy.
