and the body of Jezebel shall be as dung upon the face of the field in the portion of Jezreel, so that they shall not say, This is Jezebel.

But Rabshakeh said unto them, Hath my master sent me to thy master, and to thee, to speak these words? hath he not'sent me to the men that sit on the wall, to eat their own dung, and to drink their own water with you?
