isaiah 36:12 But Rabshakeh said, 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 upon the wall, that they may eat their own dung, and drink their own piss with you? - Free Bible Online

      12. Is it to thy master and thee that I am sent? Nay, it is to the men on the wall, to let them know (so far am I from wishing them not to hear, as you would wish), that unless they surrender, they shall be reduced to the direst extremities of famine in the siege (2Ch 32:11, explains the word here), namely, to eat their own excrements: or, connecting, "that they may eat," &c., with "sit upon the wall"; who, as they hold the wall, are knowingly exposing themselves to the direst extremities [MAURER]. Isaiah, as a faithful historian, records the filthy and blasphemous language of the Assyrians to mark aright the true character of the attack on Jerusalem.
