Genesis 22:12-13

12He said, “Do not reach out your hand against the boy, and do not do anything to him; for now 1I know that you 2fear God, since you have not withheld 3your son, your only son, from Me.”

13Then Abraham raised his eyes and looked, and behold, behind him was a ram caught in the thicket by its horns; and Abraham went and took the ram and offered it up as a burnt offering in the place of his son.
