Leviticus 14:8, 10

“The persons being purified must then wash their clothes, shave off all their hair, and bathe themselves in water. Then they will be ceremonially clean and may return to the camp. However, they must remain outside their tents for seven days.

“On the eighth day each person being purified must bring two male lambs and a one-year-old female lamb, all with no defects, along with a grain offering of six quarts of choice flour moistened with olive oil, and a cup of olive oil.
