DaasYochid:
Interesting thought (oh no) I had over Shabbos.
The ???? says ????? ???? .. ?? ????? ???? ??????. There are two ways to explain. One, Rashi (and Medrash), they’re referring to Tziporah, and they were dismayed at Moshe’s apparent “holier then thou” attitude. The other view, Rashbam and others, states they were referring to the queen of Kush, whom they gave to Moshe to remarry (he did not). So according to this view they were dismayed at Moshe’s abandon, his liberty due to his lofty position…
Two opposing views.. so relevant today.. Either too religious or too lax.
