Genesis 22:7-11

Isaac said to his father Abraham, “Father!” Abraham answered, “Yes, my son.” Isaac said, “We have the fire and the wood, but where is the lamb we will burn as a sacrifice?” Abraham answered, “God will give us the lamb for the sacrifice, my son.” So Abraham and his son went on together and came to the place God had told him about. Abraham built an altar there. He laid the wood on it and then tied up his son Isaac and laid him on the wood on the altar. Then Abraham took his knife and was about to kill his son. But the angel of the LORD called to him from heaven and said, “Abraham! Abraham!” Abraham answered, “Yes.”
