Genesis 22:1-3

1And it came to pass after these things, that God tested Abraham, and said to him, Abraham: and he said, Behold, here I am .1 2And he said, Take now thy son, thy only son Isaac, whom thou lovest, and go into the land of Moriah; and offer him there for a burnt offering upon one of the mountains which I will tell thee of.

3And Abraham rose early in the morning, and saddled his donkey, and took two of his young men with him, and Isaac his son, and cut up the wood for the burnt offering, and rose, and went to the place which God had told him.
