The miraculous rescue of Abraham from death by starvation and thirst convinced the prison-keeper of the truth of God and His prophet Abraham, and he acknowledged his belief in both publicly. The king's threat of death unless he recanted could not turn him away from his new and true faith. When the hangman raised his sword and set it at his throat to kill him, he exclaimed, "The Eternal He is God, the God of the whole world as well as of the blasphemer Nimrod." But the sword could not cut his flesh. The harder it was pressed against his throat, the more it broke into pieces.
