'Warming' in the Bible

“In fact, they are like stubble;Fire burns them.They cannot save themselves from the power of the flame [much less save the nation],There is no blazing coal for warmingNor fire before which to sit!

Peter had followed Him at a distance, right into the courtyard of the high priest; and he was sitting with the officers [guards and servants] and warming himself at the fire.

and when she saw Peter warming himself, she looked intently at him and said, “You were with Jesus the Nazarene, too.”

Now the servants and the officers had made a fire of coals, because it was cold, and they were standing and warming themselves. And Peter was with them, standing and warming himself.

Now Simon Peter was [still] standing and warming himself. So they said to him, “You are not one of His disciples, are you?” He denied it and said, “I am not.”
