UKJV⁽ⁱ⁾ ³⁵ And thus shall you do unto Aaron, and to his sons, according to all things which I have commanded you: seven days shall you consecrate them. ³⁶ And you shall offer every day a bullock for a sin offering for atonement: and you shall cleanse the altar, when you have made an atonement for it, and you shall anoint it, to sanctify it. ³⁷ Seven days you shall make an atonement for the altar, and sanctify it; and it shall be an altar most holy: whatsoever touches the altar shall be holy.
