'Cleanse' in the Bible

“Take the Levites from among the sons of Israel and cleanse them.

This is what you shall do to them to [ceremonially] cleanse them: sprinkle the water of purification on them, and let them use a razor over their whole body and wash their clothes, and they will be clean.

The Levites, too, purified themselves from sin and they washed their clothes; and Aaron presented them as a wave offering before the Lord, and Aaron made atonement for them to cleanse them.
