Genesis 22:9-18

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.” The angel said, “Don’t kill your son or hurt him in any way. Now I can see that you trust God and that you have not kept your son, your only son, from me.” Then Abraham looked up and saw a male sheep caught in a bush by its horns. So Abraham went and took the sheep and killed it. He offered it as a whole burnt offering to God, and his son was saved. So Abraham named that place The LORD Provides. Even today people say, “On the mountain of the LORD it will be provided.” The angel of the LORD called to Abraham from heaven a second time and said, “The LORD says, ‘Because you did not keep back your son, your only son, from me, I make you this promise by my own name: I will surely bless you and give you many descendants. They will be as many as the stars in the sky and the sand on the seashore, and they will capture the cities of their enemies. Through your descendants all the nations on the earth will be blessed, because you obeyed me.’ ”
