9 When they came to the place that God had shown him, Abraham built an altar there and laid the wood in order. He bound his son Isaac, and laid him on the altar, on top of the wood. 10 Then Abraham reached out his hand and took the knife to killa his son. 11 But the angel of the Lord called to him from heaven, and said, “Abraham, Abraham!” And he said, “Here I am.” 12 He said, “Do not lay your hand on the boy or do anything to him; for now I know that you fear God, since you have not withheld your son, your only son, from me.” 13 And Abraham looked up and saw a ram, caught in a thicket by its horns. Abraham went and took the ram and offered it up as a burnt offering instead of his son. 14 So Abraham called that place “The Lord will provide”;b as it is said to this day, “On the mount of the Lord it shall be provided.”c

15 The angel of the Lord called to Abraham a second time from heaven, 16 and said, “By myself I have sworn, says the Lord: Because you have done this, and have not withheld your son, your only son, 17 I will indeed bless you, and I will make your offspring as numerous as the stars of heaven and as the sand that is on the seashore. And your offspring shall possess the gate of their enemies, 18 and by your offspring shall all the nations of the earth gain blessing for themselves, because you have obeyed my voice.”
