Leviticus 14:12-13

Webster(i) 12 And the priest shall take one he-lamb, and offer him for a trespass-offering, and the log of oil, and wave them for a wave-offering before the LORD. 13 And he shall slay the lamb in the place where he shall kill the sin-offering and the burnt-offering, in the holy-place: for as the sin-offering is the priest's, so is the trespass-offering: it is most holy.
