'Be Clean' in the Bible

Thus you shall do to them, for their cleansing: sprinkle purifying water on them, and let them use a razor over their whole body and wash their clothes, and they will be clean.

That one shall purify himself from uncleanness with the water on the third day and on the seventh day, and then he will be clean; but if he does not purify himself on the third day and on the seventh day, he will not be clean.

Then 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 him from uncleanness, and he shall wash his clothes and bathe himself in water and shall be clean by evening.

everything that can stand the fire, you shall pass through the fire, and it shall be clean, but it shall be purified with water for impurity. But whatever cannot stand the fire you shall pass through the water.

And you shall wash your clothes on the seventh day and be clean, and afterward you may enter the camp.”
