Jesus' response was a blow to the Pharisees
traditions.

The disciples asked Jesus, "Knowest thou that
the Pharisees were offended, after they heard
this saying?" Matthew 15:12

Jesus calmed them, saying, ". . . .Every plant,
which my heavenly Father hath not planted,
shall be rooted up. Let them alone: they be
blind leaders of the blind. And if the blind lead
the blind, both shall fall into the ditch"
Matthew 15:13-14
