'Warming' in the Bible

Peter followed Jesus at a distance, as far as the outer court of the High Priest's palace. But there he remained sitting among the officers, and warming himself by the fire.

and seeing Peter warming himself she looked at him and said, "You also were with Jesus, the Nazarene."

Now because it was cold the servants and the police had lighted a charcoal fire, and were standing and warming themselves; and Peter too remained with them, standing and warming himself.

But Simon Peter remained standing and warming himself, and this led to their asking him, "Are you also one of his disciples?" He denied it, and said, "No, I am not."
