Genesis 22:1-3

1After these things God tested Abraham and said to him, “Abraham!” “Here I am,” he answered.

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

3So Abraham got up early in the morning, saddled his donkey, and took with him two of his young men and his son Isaac. He split wood for a burnt offering and set out to go to the place God had told him about.
