Leviticus 14:8, 10

And he that 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 shall come into the camp, but shall dwell outside his tent seven days.

And on the eighth day he shall take two he-lambs without blemish, and one ewe-lamb a year old without blemish, and three tenth parts of an ephah of fine flour for a meal-offering, mingled with oil, and one log of oil.
