Genesis 22:9-11

Wycliffe Bible

⁹ and came to the place which God had showed to him; in which place Abraham builded an altar, and dressed [the] wood above; and when he had bound (al)together Isaac, his son (and when he had bound up his son Isaac), he laid Isaac on the altar, upon the heap of wood.

¹⁰ And he held forth his hand, and took the sword to sacrifice his son. (And he stretched forth his hand, and took the knife to sacrifice his son.)

¹¹ And lo! the angel of the Lord cried from heaven, and said, Abraham! Abraham! Which answered, I am present (I am here).
