'Fire' in the Bible

And the tongue is [in a sense] a fire, the very world of injustice and unrighteousness; the tongue is set among our members as that which contaminates the entire body, and sets on fire the course of our life [the cycle of man’s existence], and is itself set on fire by hell (Gehenna).

Your gold and silver are corroded, and their corrosion will be a witness against you and will consume your flesh like fire. You have stored up your treasure in the last days [when it will do you no good].
