Leviticus 14:8, 10

And he who is to be cleansed shall wash his clothes and shave off all his hair and bathe himself in water, and he shall be clean. And after that he may come into the camp, but live outside his tent seven days.

“And on the eighth day he shall take two male lambs without blemish, and one ewe lamb a year old without blemish, and a grain offering of three tenths of an ephah of fine flour mixed with oil, and one log of oil.
