'Fire' in the Bible

Thus also the tongue is a little member, and boasts great things. See how little a fire, how large a wood it kindles!

and the tongue is fire, the world of unrighteousness; the tongue is set in our members, the defiler of the whole body, and which sets fire to the course of nature, and is set on fire of hell.

Your gold and silver is eaten away, and their canker shall be for a witness against you, and shall eat your flesh as fire. Ye have heaped up treasure in the last days.
