OK, we’ve beaten this linguistic horse to death. Maybe we ought to see what the narrative reveals. After all, according to my training, narrative context overrides grammar and semantics every time. So here goes my version of the story (which I have happily embellished).
Once upon a time an man named Abram was ordered to go to Canaan (12:1) in return for which YHWH issued His first promise to Abram, a promise to make Abram the Patriarch of a great nation (12:2). So Abram packed up all that he and his nephew had and took off. After they had arrived in Shechem YHWH appeared again and issued a second promise by offering to Abram all of the land of Canaan (12:7).
After some time, including a sojourn to Egypt and an uncomfortable separation of Lot, YHWH again appeared to Abram and repeated His promise, this time more detailed and grandiose from the first and second promises (13:13-17).
After a time, Abram’s nephew Lot was captured by the 5 Kings and Abram went to war, rescued Lot by defeating Lot’s captors. Abram then returned the spoils to Melchizedek who then blessed Abram.
But YHWH noticed that, despite Abram’s victory, Abram was uneasy, Anxious. Maybe even frightened or concerned that the 5 kings would rise up and come after him. Wishing to quell Abram’s anxiety, YHWH came to Abram and told him not to be afraid and that YHWH would protect him.
But then something strange happens. For reasons not clear, YHWH issues a totally different promise. A promise of protection. Protection from what? Abram had already defeated the 5 kings and protection was the last thing he needed. What about the land? What about the children? So he reminds YHWH,
"Promises, shromises. Where is the land, where are my descendants?.
But now Abram does the unthinkable. He challenges YHWH to live up to His promises.
“Behold!!!” says Abram, “You have given me no offspring as you have promised lo these many years and now I have nothing and when I die none of my possessions will go to my heirs.”
But, what does YHWH do? Yet again is repeats His promise to Abram (15:5) but in even more grandiose terms. Abram will have nothing of this. To himself he says, “Did He even hear what I’ve said? I recognizes that YHWH speaks the truth, but my faith has about run out.(15:6) but how long must I wait?”
But now YHWH is angry and plays His authority card, “I, not you, am the LORD here.”
Abram doesn’t back down and continues to challenge YHWH. “LORD, SHMORD. if you ever do get around to delivering on your promise, how will I even know this land is mine.”
YHWH has had enough. He puts Abram into a trance (15:13) and orders him to have faith. But YHWH is not done. He punishes Abram for his doubt. He decrees that Abram’s offspring will still come, but now must first suffer under Egypt’s lash. YHWH will then repatriate Abram’s descendants and, as for Abram, YHWH promises that he will live a long life.
After this experience, Abram is changed. No longer is He so vocal about his lack of faith, but when God later repeats His promise in much less grandiose terms, just a son, Abraham laughs silently to himself thinking that Sarah is too old to bear children. Abraham appears to have given up his faith in God’s ability to deliver on his promises. (17:18).
But this all changes. After a time, Sarah gives birth to Isaac and after Isaac is grown into a boy, God calls to Abraham and asks him to sacrifice his son.
Abraham, please go to Moriah and sacrifice your son. Without objection.
Now, something has changed in Abraham. Possibly it was the birth of his son but in any case without objection is sets out to murder his son at God’s request. But when the moment comes as Abraham raises his hand to plunge the dagger into his son, he is stopped by a voice that says,
"Stop. Do not murder your son because now I know you fear God.
The story is about a man whose faith originally depended on worldly things - land and descendants, and ends when Abraham demonstrates his faithfulness without the promise of reward. In Jewish tradition this story is called the “Aqedah,” and by Christians is known as “The Binding of Isaac.”
