plunder speedeth; spoil hasteth, (Isa. 8:1-3; compare 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.
