Mateus 15:14

They be blind leaders of the blind. — It would appear from Romanos 2:19 that the phrase was one in common use to describe the ideal of the Rabbi’s calling. Now they heard it in a new form, which told them that their state was the very reverse of that ideal. And that which was worst in it was that their blindness was self-chosen (Mateus 13:15), and that they were yet all unconscious of it, and boasted that they saw (João 9:41).

If the blind lead the blind, both shall fall into the ditch. — The proverb was probably a familiar one (it is given in St. Lucas 6:39 as part of the Sermon on the Plain), but, as now spoken, it had the character of a prophecy. We have but to read the Jewish historian’s account of the years that preceded the destruction of Jerusalem to see what the “ditch” was towards which teachers and people were alike blindly hastening. Bitter sectarianism, and wild dreams, and baseless hopes, and maddened zeal, and rejection of the truth which alone had power to save them, this was the issue which both were preparing for themselves, and from which there was no escape.
