'Purified' in the Bible

And the Levites purified themselves from sin, and they washed their garments; and Aaron offered them as a wave-offering before Jehovah; and Aaron made atonement for them to cleanse them.

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.
