'Firelight' in the Bible

Look, they are like straw, which the fire burns up; they cannot rescue themselves from the heat of the flames. There are no coals to warm them, no firelight to enjoy.

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.

When a servant saw him sitting in the firelight, and looked closely at him, she said, “This man was with Him too.”
