Leviticus 14:11-13

¹¹And the priest who cleanseth shall cause the man that is to be made clean, and these things, to stand before the Lord, at the door of the tabernacle of the congregation:

¹²And the priest shall take the one sheep, and offer the same for a trespass-offering, with the log of oil; and he shall make with them a waving before the Lord.

¹³And he shall slay the sheep on the place where the sin-offering and the burnt-offering are killed, in the holy place; for as the sin-offering so doth the trespass-offering belong to the priest: it is most holy.
