Leviticus 14:13

Then he is to slaughter the lamb in the sanctuary area where the sin offering and burnt offering are slaughtered. Like the sin offering, the guilt offering belongs to the priest; it is most holy.

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:

He shall kill the male lamb in the place where they kill the sin offering and the burnt offering, in the place of the sanctuary; for as the sin offering is the priest’s, so is the trespass offering. It is most holy.

and he shall kill the he-lamb in the place where they kill the sin-offering and the burnt-offering, in the place of the sanctuary: for as the sin-offering is the priest’s, so is the trespass-offering: it is most holy.
