Leviticus 14:12-13

12The priest is to take one male lamb and present it as a guilt offering, along with the one-third quart of olive oil, and he will present them as a presentation offering before the Lord.

13He is to slaughter the male lamb at the place in the sanctuary area where the sin offering and burnt offering are slaughtered, for like the sin offering, the guilt offering belongs to the priest; it is especially holy.
