Genesis 22:7-11

“Father?” Isaac broke the silence. “Yes, my son,” Abraham replied. “We have the wood and the fire,” Isaac said, “but where is the lamb for the burnt offering?” Abraham answered, “My son, God himself will provide the lamb for an offering.” So they went on together. When they arrived at the place on Mount Moriah that God had shown him, Abraham built an altar and stacked the wood on it. He tied up his son Isaac and laid him on top of the wood on the altar. Then Abraham took the knife in his hand to plunge it into his son, but the angel of YAHWEH called to him from heaven, saying, “Abraham! Abraham!” “Yes, I’m here,” he answered.
