Isaiah 24:12 - Albert Barnes' Notes on the Bible

And the gate is smitten with destruction - The word rendered ‘destruction’ may denote ‘a crash’ (Gesenius). The idea is, that the gates of the city, once so secure, are how battered down and demolished, so that the enemy ran enter freely. Thus far is a description of the calamities that would come upon the nation. The following verses show that, though the desolation would be general, a few of the inhabitants would be left - circumstance thrown in to mitigate the prospect. of the impending ruin.
