Genesis 22:4-10

22:4 On the third day Abraham caught sight of the place in the distance. 22:5 So he said to his servants, “You two stay here with the donkey while the boy and I go up there. We will worship and then return to you.”

22:6 Abraham took the wood for the burnt offering and put it on his son Isaac. Then he took the fire and the knife in his hand, and the two of them walked on together. 22:7 Isaac said to his father Abraham, “My father?” “What is it, my son?” he replied. “Here is the fire and the wood,” Isaac said, “but where is the lamb for the burnt offering?” 22:8 “God will provide for himself the lamb for the burnt offering, my son,” Abraham replied. The two of them continued on together.

22:9 When they came to the place God had told him about, Abraham built the altar there and arranged the wood on it. Next he tied up his son Isaac and placed him on the altar on top of the wood. 22:10 Then Abraham reached out his hand, took the knife, and prepared to slaughter his son.
