'Fire' in the Bible

Therefore he said unto his servants, See, Joab's field is near mine, and he hath barley there; go and set it on fire. And Absalom's servants set the field on fire.

Then Joab arose, and came to Absalom unto his house, and said unto him, Wherefore have thy servants set my field on fire?

There went up a smoke out of his nostrils, and fire out of his mouth devoured: coals were kindled by it.

Through the brightness before him were coals of fire kindled.

But the man that shall touch them must be fenced with iron and the staff of a spear; and they shall be utterly burned with fire in the same place.
