'Be Clean' in the Bible

And if the woman is not defiled, but is clean, then she shall be clean, and shall conceive seed.

He shall purify himself with it on the third day, and on the seventh day he shall be clean. But if he does not purify himself the third day, then the seventh day he shall not be clean.

And the clean person shall sprinkle on the unclean on the third day, and on the seventh day. And on the seventh day he shall purify himself, and wash his clothes, and bathe himself in water. And he shall be clean at evening.

everything that can stand the fire, you shall make go through the fire, and it shall be clean. Only it shall be purified with the water of separation. And all that cannot stand the fire you shall make go through the water.

And you shall wash your clothes on the seventh day, and you shall be clean, and afterwards you shall come into the camp.

So you shall not defile the land in which you are. For blood defiles the land. And the land cannot be cleansed of the blood that is shed in it, except by the blood of him that shed it.
