'Cleanse' in the Bible

and there doth come to him a leper, calling on him, and kneeling to him, and saying to him -- 'If thou mayest will, thou art able to cleanse me.'

and when they come from the market place, they do not eat unless they cleanse themselves; and there are many other things which they have received in order to observe, such as the washing of cups and pitchers and copper pots.)
