'Be Clean' in the Bible

But if the woman have not been defiled, and be clean, then she shall be clear, 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 purify not himself the third day, then the seventh day he shall not be clean.

and the clean shall sprinkle it on the unclean on the third day, and on the seventh day; and he shall purify him on the seventh day; and he shall wash his garments, and bathe himself in water, and shall be clean at even.

everything that passeth through the fire, ye shall make it go through the fire, and it shall be clean; only it shall be purified with the water of separation; and everything that cannot pass through the fire ye shall make go through the water.

And ye shall wash your garments on the seventh day, and ye shall be clean; and afterwards ye may come into the camp.
