Leviticus 14:12-13

12And the priest shall take one he-lamb, and present it for a trespass-offering, and the log of oil, and wave them as a wave-offering before Jehovah.

13And he shall slaughter the he-lamb at the place where the sin-offering and the burnt-offering are slaughtered, in a holy place; for as the sin-offering, so the trespass-offering is the priest's: it is most holy.
