Genesis 22:11-13

Just then an angel of GOD called to him out of Heaven, “Abraham! Abraham!” “Yes, I’m listening.” “Don’t lay a hand on that boy! Don’t touch him! Now I know how fearlessly you fear God; you didn’t hesitate to place your son, your dear son, on the altar for me.” Abraham looked up. He saw a ram caught by its horns in the thicket. Abraham took the ram and sacrificed it as a burnt offering instead of his son.
