Isaías 33:11-12

The Judahites had done their best to bring forth victory through their own efforts, but all they yielded was chaff and stubble, nothing substantial. Now God would thoroughly consume the little that they were able to produce. It is possible that the Lord addressed Assyria in these verses, but I think Judah is the more probable "you." He would also destroy Israel’s enemies as thoroughly as limestone and thorns.

"The tragedy of sin is that it ruins the life of the sinner; the danger of sin is that it excites the wrath of God." [Note: Motyer, p. 265.]
