An elderly Jewish gentleman, Harry Goldstein, who somehow passed his driving test, is driving the wrong way down the freeway. His wife calls him up and says, “Harry, I just heard on the news there’s someone driving a black Cadillac the wrong way down the Interstate freeway and I just wanted to check that it’s not you.” “Yeah,” says Harry, “I heard it too, but the highway I’m driving on, it’s not just one car going the wrong way — the whole highway’s going the wrong way!”
The Jewish People have been driving the ‘wrong way’ down the world’s highway for more than three and a half thousand years. Avraham is called ‘HaIvri,’ from which the name Hebrew derives, but it also means ‘the one who crossed over’. While the world at large has been cruising down the highway of status, money, fame, and physical indulgence, the Jewish nation has spent those millennia driving the ‘wrong way’ up that highway to proclaim the idea of a Supreme Being to whom all our actions are ultimately accountable and Who desires and demands a world of justice, self-restraint, morality, peace, and equality.
“...everything that has fins and scales in the water, the seas, and in the streams, those may you eat…” (11:9)
