It's a bit easier to understand when we look at the whole paragraph:
Isaiah 29:17 Is it not yet a very little while,
and Lebanon shall be turned into a fruitful field,
and the fruitful field shall be esteemed as a forest?
18 And in that day shall the deaf hear the words of the book,
and the eyes of the blind shall see out of obscurity,
and out of darkness.
19 The meek also shall increase their joy in the Lord,
and the poor among men shall rejoice in the Holy One of Israel.
20 For the terrible one is brought to nought,
and the scorner is consumed,
and all that watch for iniquity are cut off:
21 that make a man an offender for a word,
and lay a snare for him that reproveth in the gate,
and turn aside the just for a thing of nought.
In that context, it would seem that what you said is correct. It makes sense to me but I could be wrong, too.
