King James Bible

And the LORD sent an angel, which cut off all the mighty men of valour, and the leaders and captains in the camp of the king of Assyria. So he returned with shame of face to his own land. And when he was come into the house of his god, they that came forth of his own bowels slew him there with the sword.

For the leaders of this people cause them to err; and they that are led of them are destroyed.

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