Genesis 22:12-13

12Then He said, “Do not reach out your hand against the young man—do nothing to him at all. For now I know that you are one who fears God—you did not withhold your son, your only son, from Me.”

13Then Abraham lifted up his eyes and behold, there was a ram, just caught in the thick bushes by its horns. So Abraham went and took the ram, and offered it up as a burnt offering instead of his son.
