Major Jewish commentators ignored the fraternal tension Onkelos flagged

Evidence

It has long been a commonplace of biblical interpretation that any additional or repetitive information in the case of a text that is otherwise so sparse and concise must itself signify, minimally, that it requires some consideration. All the more reason to be surprised at the lack of interest that seems to have been felt by the major Jewish commentators. Onkelos’s manifest anxiety could have set off an exegetical conversation. It did not. — Gil Anidjar, The Jew, the Arab, 330

• QUESTION: Why did the major commentators pass over the brother/kinship ambiguity that Onkelos found genuinely disturbing? Anidjar leaves this open as a hook.
