Leviticus 14:7-10

7He will sprinkle the blood seven times on the one to be cleansed and will declare that person clean. Then he will let the living bird fly away into the open country.

8“The one to be cleansed must wash his clothes, shave off all his hair, and wash. Then he will be clean. After that he may go into the camp. However, for seven days he will live outside his tent.

9On the seventh day he must shave off all the hair on his head, his beard, and his eyebrows, and he must wash his clothes and body. Then he will be clean.

10“On the eighth day he must take two male lambs that have no defects and a one-year-old female lamb that has no defects. He must also take eight cups of flour mixed with olive oil for a grain offering along with a quart of olive oil.
