Genesis 22:1-3

Now it came about after these things, that God tested Abraham, and said to him, “Abraham!” And he said, “Here I am.” He said, “Take now your son, your only son, whom you love, Isaac, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I will tell you.” So Abraham rose early in the morning and saddled his donkey, and took two of his young men with him and Isaac his son; and he split wood for the burnt offering, and arose and went to the place of which God had told him.
