Genesis 22:1-3

1Now it came to pass after these things that God tested Abraham, and said to him, “Abraham!” And he said, “Here I am.”

2Then He said, “Take now your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you.”

3So 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 the wood for the burnt offering, and arose and went to the place of which God had told him.
