'Blind Guides' in the Bible

Leave them alone. They are blind guides! But if one blind man leads another, they will both fall into the ditch!"

Alas for you, you blind guides, who say, 'If anyone swears by the sanctuary, it does not matter, but if anyone swears by the gold of the sanctuary, it is binding.'

You blind guides! straining out the gnat, and yet swallowing the camel!
