In 2018 Globe's Hamlet, Polonius looked like a Jew. When watching the first act I felt puzzled: was there any evidence in the playtext to imply that he should be a Jew? Then, when it came to Act 2 Scene 2, when Polonius interrupted the 1 Player, saying the monologue is too long, Hamlet said "It shall to the barber's with your beard." Suddenly, it all makes sense now. Apparently, Polonius won't easily cut his beard because he's a Jew, therefore, Hamlet's words was an insult!
There're many stories in the Hebrew Bible concerning cutting one's hair or beard. David's missionaries, when degraded, were cut their beards by the enemies. Samson, a Nazirite, never cut his hair because that represented his covenant with the God in some senses. Absalom, a narcissist, regularly cut his own beautiful hair and in the end he died because his head stuck in the branches of a tree; his beautiful hairs hanging in the air.
This new interpretation that Polonius is a Jew may shed new light on Hamlet's sanity: he's quite reasonable, considerate even, when he inquired Polonius about Ophelia, alluding to the Jephthah's story. Jephthah was a Judge of Israel, after all.
