'Cleanse' in the Bible

And I have sprinkled over you clean water, And ye have been clean; From all your uncleannesses, and from all your idols, I do cleanse you.

And the house of Israel have buried them -- in order to cleanse the land -- seven months.

And men for continual employment they separate, passing on through the land, burying with those passing by those who are left on the face of the earth, to cleanse it: at the end of seven months they search.
