Leviticus 14:8, 10

“The person to be cleansed must wash their clothes, shave off all their hair and bathe with water; then they will be ceremonially clean. After this they may come into the camp, but they must stay outside their tent for seven days.

“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.
