Matthew 15:14
Let them alone; they are blind guides. And if the blind lead the blind, both will fall into a pit. The blind guides — the Pharisees who cannot see the distinction between the commandment of God and the tradition of men — will lead those who follow them into the same blindness. The pit that both the guide and the guided fall into is the eschatological judgment that follows from the heart's distance from God (verse 8).
