'Cleanse' in the Bible

"Take the Levites from among the children of Israel, and cleanse them.

You shall do this to them, to cleanse them: sprinkle the water of cleansing on them, let them shave their whole bodies with a razor, and let them wash their clothes, and cleanse themselves.

"After that, the Levites shall go in to do the service of the Tent of Meeting: and you shall cleanse them, and offer them as a wave offering.

The Levites purified themselves from sin, and they washed their clothes; and Aaron offered them for a wave offering before Yahweh; and Aaron made atonement for them to cleanse them.
