Leviticus 14:10-11

“And on the eighth day he shall take two male lambs without blemish, and one ewe lamb a year old without blemish, and a grain offering of three tenths of an ephah of fine flour mixed with oil, and one log of oil. And the priest who cleanses him shall set the man who is to be cleansed and these things before the LORD, at the entrance of the tent of meeting.
