Leviticus 14:12-13

Thomson(i) 12 and the priest shall take one of the male lambs, and offer it for a trespass offering, with the cotulus of oil, and set them apart as a dedication before the Lord; 13 [Now they shall kill the lamb in the place where they kill the whole burnt offerings and the sin offerings; in a holy place] for as is the sin offering, so is the trespass offering, for the priest. They are most holy.
