AND the angel of the LORD called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. And he said, Lay not thine hand upon the lad, neither do thou any thing unto him: for now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from me.* And Abraham lifted up his eyes, and looked, and behold behind him a ram caught in a thicket by his horns: and Abraham went and took the ram, and offered him up for a burnt offering in the stead of his son. And Abraham called the name of that place Jehovah-jireh: as it is said to this day, In the mount of the LORD it shall be seen.
* If we accept the Talmudic interpretation mentioned earlier, God is not praising Abraham for being ready to sacrifice Isaac. He is praising him for going through the whole charade without at any time thinking that Isaac was at risk — a man of less faith might have played it safe, just in case God was of like mind to Baal and other cruel deities.
