'Pollute' in the Bible

And ye shall bear no sin by reason of it, when ye have heaved from it the best of it: neither shall ye pollute the holy things of the children of Israel, lest ye die.

'When a man voweth a vow to Jehovah, or hath sworn an oath to bind a bond on his soul, he doth not pollute his word; according to all that is going out from his mouth he doth.

So ye shall not pollute the land wherein ye are: for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it.
