'Be Clean' in the Bible

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

the same shall purify himself therewith 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 person shall sprinkle upon the unclean on the third day, and on the seventh day: and on the seventh day he shall purify him; and he shall wash his clothes, and bathe himself in water, and shall be clean at even.

everything that may abide the fire, ye shall make to go through the fire, and it shall be clean; nevertheless it shall be purified with the water for impurity: and all that abideth not the fire ye shall make to go through the water.

And ye shall wash your clothes on the seventh day, and ye shall be clean; and afterward ye shall come into the camp.
