'Fire' in the Bible

So also the tongue is a small member [of the body] and boasts great [things]. Behold how small a fire sets ablaze how great a forest!

And the tongue [is] a fire! The world of unrighteousness, the tongue, is set among our members, defiling the whole body and setting on fire {the course of human existence}, being set on fire by hell.

Your gold and silver have become corroded, and their corrosion will be a witness against you, and it will consume your flesh like fire. You have stored up treasure in the last days.
