Genesis 22:1-3

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

2And he said, Take now thy son, thine only [son], whom thou lovest, Isaac, and get thee into the land of Moriah, and there offer him up for a burnt-offering on one of the mountains which I will tell thee of.

3And Abraham rose early in the morning, and saddled his ass, and took two of his young men with him, and Isaac his son; and he clave the wood for the burnt-offering, and rose up and went to the place that 2God had told him of.
