Abraham did not withhold Isaac from God: Genesis 22

v12 Now I know that you FEAR God because you have not withheld your only son from me.

v16 I SWEAR because you have done this and have not withheld your only son, I will surely BLESS you.

– Your descendants will be NUMEROUS as the stars, and as the sand in the sea shore, will take POSSESSION of their enemies GATES and all NATIONS on earth will be BLESSED because you have OBEYED me.
