Plunder speedeth; spoil hasteth, (Isa. 8:1-3; comp. Zeph. 1:14), a name Isaiah was commanded first to write in large characters on a tablet, and afterwards to give as a symbolical name to a son that was to be born to him (Isa. 8:1, 3), as denoting the sudden attack on Damascus and Syria by the Assyrian army.
