'Fire' in the Bible

If anyone does not remain in Me, he is thrown aside like a branch and he withers. They gather them, throw them into the fire, and they are burned.

Now the slaves and the temple police had made a charcoal fire, because it was cold. They were standing there warming themselves, and Peter was standing with them, warming himself.

When they got out on land, they saw a charcoal fire there, with fish lying on it, and bread.
