'Fire' in the Bible

And the tongue is a fire. That world of iniquity, the tongue, is placed within us spotting and soiling our whole nature, and setting the whole round of our lives on fire, being itself set on fire by Gehenna.

your gold and your silver have become covered with rust, and the rust on them will give evidence against you, and will eat your flesh like fire. You have hoarded up wealth in these last days.
