Berĕshith (Genesis) 22:10-13

And Aḇraham stretched out his hand and took the knife to slay his son, but the Messenger of יהוה called to him from the heavens and said, “Aḇraham, Aḇraham!” And he said, “Here I am.” And He said, “Do not lay your hand on the boy, nor touch him. For now I know that you fear Elohim, seeing you have not withheld your son, your only son, from Me.” And Aḇraham lifted his eyes and looked and saw behind him a ram caught in a bush by its horns, and Aḇraham went and took the ram and offered it up for an ascending offering instead of his son.
