Duncan Derrett again: Jesus condemns the Pharisees and scribes as “blind men,” and their blindness is a myopia that makes it impossible for them to distinguish between gnats and camels. Both are prohibited foods, but “their throats are wide, their bellies capacious for the unclean.” For all their their obsession with cleanness, they are in fact filling themselves with dead men’s bones, defiling themselves by cannibalizing fellow Jews.
