9 When they came to the place of which God had told him, Abraham built an altar there, and laid the wood in order, and bound Isaac his son, and laid him on the altar, upon the wood. 10 Then Abraham put forth his hand, and took the knife to slay his son. 11 But the angel of the Lord called to him from heaven, and said, “Abraham, Abraham!” And he said, “Here am I.” 12 He said, “Do not lay your hand on the lad or do anything to him; for now I know that you fear God, seeing you have not withheld your son, your only son, from me.” 13 And Abraham lifted up his eyes and looked, and behold, behind him was a ram, caught in a thicket by his horns; and Abraham went and took the ram, and offered it up as a burnt offering instead of his son.
