Isaia 37:29

Because thy rage against me, and thy tumult, is come up into my ears, therefore I will put my (u) hook in thy nose, and my bridle in thy lips, and I will turn thee back by the way by which thou (x) camest.

(u) Because Sennacherib showed himself as a devouring fish and furious beast, he uses these similarities to teach how he will take him and guide him.

(x) You will lose your labour.
