Leviticus 14:7-10

7The priest will then sprinkle the blood of the dead bird seven times on the person being purified of the skin disease. When the priest has purified the person, he will release the live bird in the open field to fly away.

8“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.

9On the seventh day they must again shave all the hair from their heads, including the hair of the beard and eyebrows. They must also wash their clothes and bathe themselves in water. Then they will be ceremonially clean.

10“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.
