Belated, belated - oy, apologies! And so timely, right before Rosh Ha-Shanah, these midrashim on the akedah.
A brief word, then, about the binding of Isaac, from the vantage point of Midrash # 46 (Tanchuma, Va-Yera 23).
"What did your father do to you?" asks Sarah.
"My father took me and led me up hills and down valleys and but for God's compassion I would not be here to tell you."
Why is that the Satan, speaking in the guise of Isaac? After all, the midrash might have had it be Isaac himself, upon his return from Mt. Moriah. After all, the Satan here says only what is true, what Isaac himself might have said.
But then Isaac himself would be the cause of his own mother's death - too cruel a burden, perhaps, for even the God of the akedah to place on a child so willing to please parents, to please even a parent with the fire of wild piety in his eyes. Too unmindful a step, perhaps, for us to imagine the real, dutiful, and mostly silent Isaac taking.
Maybe the Satan generally speaks only the truth; but it's all in how you time the truth, and where you choose to speak it.
Maybe Isaac himself never would have told his mother - just as he never said 'no' to his father. Maybe he would have borne that silence, just as he bore the wood for his own pyre on his back.
Maybe Sarah didn't really need to be told by Isaac himself. Maybe the 'Satan,' speaking in her son's voice and guise, was the voice of her own consciousness, telling her what she already knew - telling her that zeal for God and mission and exclusive blessing had driven simple human goodness from her family.
She had taken part in that herself - "Banish that slave-woman and her son, lest he inherit with my Isaac!"
Abraham could not find courage in parental love. Sarah could not find security in kindness. Maybe the deadly truth in the moment of the Satan's words to Sarah in the voice of her silent son was the realization that only one person in the family had retained compassion and had not forsaken generosity, and the realization of who that was, and what the cost to him must have been.
