Genesis 22:10

7 And Isaac spoke to Abraham his father, and said, My father: and he said, here [am] I, my son. And he said, Behold the fire and the wood: but where [is] the lamb for a burnt-offering?

8 And Abraham said, My son, God will provide himself a lamb for a burnt-offering: so they went both of them together.

9 And they came to the place which God had named to him; and 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 And Abraham stretched forth his hand, and took the knife to slay his son.

11 And the angel of the LORD called to him from heaven, and said, Abraham, Abraham. And he said, Here [am] I.

12 And he said, Lay not thy hand upon the lad, neither do thou any thing to him: for now I know that thou fearest God, seeing thou hast not withheld from me thy son, thy only [son].

13 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 for a burnt-offering in the stead of his son.
