Jerome : (Verse 27-28.) Zion will be redeemed by justice, and they will bring her back to righteousness. And it will crush the wicked and sinners together; and those who have forsaken the Lord will be consumed. Not all will be redeemed, nor will all be saved, but only the remnant, as mentioned before. However, they will be brought back to righteousness once the wicked and sinners have been crushed, and those who have forsaken the Lord will be consumed. — Commentary on Isaiah
