אבן עזרא — בן סורר ומורה / סמיכות לאשת יפת תאר

Q — The parsha of ben sorer u'moreh sits adjacent to the parsha of eshet yefat to'ar. Is the placement merely organizational, or does it teach something substantive about the cause-and-effect chain that produces a rebellious child?

A — For Ibn Ezra the adjacency is causal — the mother shapes the child decisively, and an "אשת יפת תאר" may produce a "בן סורר ומורה." He brings two cryptic proofs, captured in the phrase "והעד: 'ושם אמו', והרמז שרמזתי בבני אהרן." (1) The מקלל (Vayikra 24:10-11) is identified not just as the son of an Egyptian father but as "בן האשה הישראלית... ושם אמו שלמית בת דברי למטה דן" — the unusual recording of the mother's name signals that the source of the cursing-son's corruption was maternal. Bad mother → bad son. (2) The contrasting positive proof: Aharon's selection for kehunat olam is traced (Shemot 6:23, 28:1) to his marriage to Elisheva sister of Nachshon Nasi of Yehudah — and Ibn Ezra explicitly states there "הזכיר אחות נחשון בעבור סוד הכהונה" and "תבואת הזרע תשתנה בהשתנות המקומות, על כן נבחרו בני אהרן לכהנת עולם." Good mother → good son, with a dynasty's worth of consequence. The two cases bracket the principle: maternal influence is decisive. And the adjacent placement of yefat to'ar before ben sorer u'moreh warns the father who is following his desires — that there is a downstream cost to whom he marries, paid in the next generation's rebellion. A peshat of pedagogical biology embedded in the parshiyot's order.
