βόθυνος

And he spake a parable unto them, Can the blind lead the blind? shall they not both fall into the ditch?

And he said unto them, What man shall there be among you, that shall have one sheep, and if it fall into a pit on the sabbath day, will he not lay hold on it, and lift it out?

Let them alone: they be blind leaders of the blind. And if the blind lead the blind, both shall fall into the ditch.
