Moses was no Jew. He was  Hebrew -- 18:26 And the LORD said: 'If I find in Sodom fifty righteous within the city then I will forgive all the place for their sake.' And He said: 'I will not destroy it if I find there forty and five.' And He said: 'I will not do it for the forty's sake.' And He said: 'I will not do it if I find thirty there.' And He said: 'I will not destroy it for the twenty's sake.' And He said: 'I will not destroy it for the ten's sake.'
