Hezron is different to Daniel in that he is scathing of the zealots and their determination to rid Israel of the Romans by force. As far as he's concerned the zealots, though claiming to be proud Jews, are really no different from the Romans. This is because they believe, like their oppressors, that what really matters in life is earthly power.
But Hezron thinks this attitude is wholly mistaken. He argues that the Law of Moses is so much more powerful than the might of the Roman Empire. The Romans' power is transient; one day, it will end. But the Law of Moses is eternal; it will always rule the hearts of every devout Jew. It is futile, then, for Daniel and the other zealots to replace one form of earthly power with another.
We can see, then, that Hezron has a completely different attitude toward life than the much more worldly Daniel. Initially, at any rate. Because, in due course, Daniel will come to be disillusioned with the violent criminal activities of Rosh and his gang of desperadoes, and will eventually follow Jesus along the path of peace. In that sense, Daniel will come to realize, like Hezron, that a higher law, however so defined, is so much more important than the temporal laws instituted by man.
