9 On the seventh day, he should shave off all the hair on his head and his chin and his eyebrows. After he shaves off all his hair, he will wash his garments and bathe himself in water, and he will be clean.

12 Such one should purify himself with the water* on the third day, and on the seventh day he will be clean. But if he does not purify himself on the third day, on the seventh day he will not be clean.

19 And you should camp outside the camp seven days. Every one of you who has killed someone* and every one of you who has touched someone slain+ should purify himself+ on the third day and on the seventh day, you and your captives.
