John Gill

And some of the Pharisees which were with him,.... Who had followed him, and were watching him, and observing what he said and did, in order to take all advantages, and every opportunity against him, they could, heard these words, and said unto him, are we blind also? they perceived he pointed at them, and therefore with indignation ask this question, taking it as a great affront unto them, to put such wise, learned, and knowing men as they in company with the ignorant and unlearned common people; see Isa 42:19.
