Genesis 22:1-9

AFTER THESE events, God tested and proved Abraham and said to him, Abraham! And he said, Here I am. [God] said, Take now your son, your only son Isaac, whom you love, and go to the region of Moriah; and offer him there as a burnt offering upon one of the mountains of which I will tell you. So Abraham rose early in the morning, saddled his donkey, and took two of his young men with him and his son Isaac; and he split the wood for the burnt offering, and then began the trip to the place of which God had told him. On the third day Abraham looked up and saw the place in the distance. And Abraham said to his servants, Settle down and stay here with the donkey, and I and the young man will go yonder and worship and come again to you. Then Abraham took the wood for the burnt offering and laid it on [the shoulders of] Isaac his son, and he took the fire (the firepot) in his own hand, and a knife; and the two of them went on together. And Isaac said to Abraham, My father! And he said, Here I am, my son. [Isaac] said, See, here are the fire and the wood, but where is the lamb for the burnt sacrifice? Abraham said, My son, God Himself will provide a lamb for the burnt offering. So the two went on together. When they came to the place of which God had told him, Abraham built an altar there; then he laid the wood in order and bound Isaac his son and laid him on the altar on the wood. [Matt. 10:37.]
