and the carcase of Jezebel shall be as dung upon the open field in the plot of Jizreel, so that they shall not say, This is Jezebel.

And Rab-shakeh said to them, Is it to thy master and to thee that my master sent me to speak these words? Is it not to the men that sit on the wall, that they may eat their own dung and drink their own urine with you?
