'Blind Guides' in the Bible

Leave them alone. They are blind guides of the blind. If the blind guide the blind, both will fall into a pit."

"Woe to you, you blind guides, who say, 'Whoever swears by the temple, it is nothing; but whoever swears by the gold of the temple, he is obligated.'

You blind guides, who strain out a gnat, and swallow a camel!
