@blaue_Fledermaus @mekkaokereke The interpretation I've read that makes the most sense to me is that the Romans would only use the left hand to hit a Jew, because the left hand was "sinister," and the right hand was reserved for equals.
If a Roman hit a Jew using the left hand, the struck cheek had to be the right cheek. But if the Jew "turned to the Roman the left cheek also," it would force the Roman to use the right hand in order to hit that left cheek.
