'Polluted' in the Bible

They say, If a man put away his wife, and she go from him, and become another man's, shall he return unto her again? Would not that land be utterly polluted? But thou hast committed fornication with many lovers; yet return to me, saith Jehovah.

Lift up thine eyes unto the heights and see, where hast thou not been lain with? In the ways hast thou sat for them, as an Arab in the wilderness; and thou hast polluted the land with thy fornications and with thy wickedness.

And it came to pass through the lightness of her fornication that she polluted the land, and committed adultery with stones and with stocks.
