Leviticus 14:9-10

9On the seventh day they must shave off all their hair; they must shave their head, their beard, their eyebrows and the rest of their hair. They must wash their clothes and bathe themselves with water, and they will be clean. 10“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.
