Leviticus 14:12-13

14:12 “The priest is to take one male lamb and present it for a guilt offering along with the log of olive oil and present them as a wave offering before the Lord. 14:13 He must then slaughter the male lamb in the place where the sin offering and the burnt offering are slaughtered, in the sanctuary, because, like the sin offering, the guilt offering belongs to the priest; it is most holy.
