Are ye so without understanding also? (Houtw kai umei asunetoi este;). See on "Mt 15:16". You also as well as the multitude. It was a discouraging moment for the great Teacher if his own chosen pupils (disciples) were still under the spell of the Pharisaic theological outlook. It was a riddle to them. "They had been trained in Judaism, in which the distinction between clean and unclean is ingrained, and could not understand a statement abrogating this" (Gould). They had noticed that the Pharisees stumbled at the parable of Jesus ( Matthew 15:12 ). They were stumbling themselves and did not know how to answer the Pharisees. Jesus charges the disciples with intellectual dulness and spiritual stupidity.
