Leviticus 14:10-13

“On the eighth day they must bring two male lambs and one ewe lamb a year old, each without defect, along with three-tenths of an ephah of the finest flour mixed with olive oil for a grain offering, and one log of oil. The priest who pronounces them clean shall present both the one to be cleansed and their offerings before the LORD at the entrance to the tent of meeting. “Then the priest is to take one of the male lambs and offer it as a guilt offering, along with the log of oil; he shall wave them before the LORD as a wave offering. He is to slaughter the lamb in the sanctuary area where the sin offering and the burnt offering are slaughtered. Like the sin offering, the guilt offering belongs to the priest; it is most holy.
