Leviticus 14:10, 11

“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.
