Genesis 22:1-9

Some time later God tested Abraham; he called to him, “Abraham!” And Abraham answered, “Yes, here I am!” “Take your son,” God said, “your only son, Isaac, whom you love so much, and go to the land of Moriah. There on a mountain that I will show you, offer him as a sacrifice to me.” Early the next morning Abraham cut some wood for the sacrifice, loaded his donkey, and took Isaac and two servants with him. They started out for the place that God had told him about. On the third day Abraham saw the place in the distance. Then he said to the servants, “Stay here with the donkey. The boy and I will go over there and worship, and then we will come back to you.” Abraham made Isaac carry the wood for the sacrifice, and he himself carried a knife and live coals for starting the fire. As they walked along together, Isaac said, “Father!” He answered, “Yes, my son?” Isaac asked, “I see that you have the coals and the wood, but where is the lamb for the sacrifice?” Abraham answered, “God himself will provide one.” And the two of them walked on together. When they came to the place which God had told him about, Abraham built an altar and arranged the wood on it. He tied up his son and placed him on the altar, on top of the wood.
