2[God] said, Take now your son, your only son Isaac, whom you love, and go to the region of Moriah; and offer him there as a burnt offering upon one of the mountains of which I will tell you.
11But the Angel of the Lord called to him from heaven and said, Abraham, Abraham! He answered, Here I am.
12And He said, Do not lay your hand on the lad or do anything to him; for now I know that you fear and revere God, since you have not held back from Me or begrudged giving Me your son, your only son.
13Then Abraham looked up and glanced around, and behold, behind him was a ram caught in a thicket by his horns. And Abraham went and took the ram and offered it up for a burnt offering and an ascending sacrifice instead of his son!
Now for the result of Abraham's (and Isaac's) obedience:
16And said, I have sworn by Myself, says the Lord, that since you have done this and have not withheld [from Me] or begrudged [giving Me] your son, your only son,
17In blessing I will bless you and in multiplying I will multiply your descendants like the stars of the heavens and like the sand on the seashore. And your Seed (Heir) will possess the gate of His enemies,
18And in your Seed [Christ] shall all the nations of the earth be blessed and [by Him] bless themselves, because you have heard and obeyed My voice.
