Brenton⁽ⁱ⁾ ³⁵ And thus shalt thou do for Aaron and for his sons according to all things that I have commanded thee; seven days shalt thou fill their hands. ³⁶ And thou shalt sacrifice the calf of the sin-offering on the day of purification, and thou shalt purify the altar when thou dost perform consecration upon it, and thou shalt anoint it so as to sanctify it. ³⁷ Seven days shalt thou purify the altar and sanctify it; and the altar shall be most holy, every one that touches the altar shall be hallowed.
