'Blind Guides' in the Bible

Let them be: they are blind guides. And if a blind man is guiding a blind man, the two will go falling into a hole together.

A curse is on you, blind guides, who say, Whoever takes an oath by the Temple, it is nothing; but whoever takes an oath by the gold of the Temple, he is responsible.

You blind guides, who take out a fly from your drink, but make no trouble over a camel.
