Bible Verses About Nitre

And one that looseth his garment in cold weather. As vinegar upon nitre, so is he that singeth songs to a very evil heart. As a moth doth by a garment, and a worm by the wood: so the sadness of a man consumeth the heart.

Though thou wash thyself with nitre, and multiply to thyself the herb borith, thou art stained in thy iniquity before me, saith the Lord God.
