Genesis 22:9-18

And they came to the place which God had told him of; and Abraham built the altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar, upon the wood. And Abraham stretched forth his hand, and took the knife to slay his son. And the angel of Jehovah called unto him out of heaven, and said, Abraham, Abraham: and he said, Here am I. And he said, Lay not thy hand upon the lad, neither do thou anything 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 the 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 Jehovah it shall be provided. And the angel of Jehovah called unto Abraham a second time out of heaven, and said, By myself have I sworn, saith Jehovah, because thou hast done this thing, and hast not withheld thy son, thine only son, that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heavens, and as the sand which is upon the sea-shore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice.
