Commentary for Isaiah 1:27

shall be redeemed through justice Since there will be in it people who practice justice.

Zion – This begins a new section now that the prophet has finished the prophecy which he spoke about Yehudah and Jerusalem from the beginning of the book until now. If you look carefully you will see that the rebuke which he delivered from the beginning of the book until the twenty first verse, which is the prophecy that particularly concerns Yehudah, was about acts between the people and Gd – sacrifices, repentance and prayer. Then most of the rebuke which he gives from the verse “How has she become a harlot…” (Isaiah 1:21) is dealing with matters between people like forgery, fraud and the perversion of justice. This is because sins against Gd were more common among the people of Yehudah who lived outside of Jerusalem, but in the capitol city of Jerusalem sins between people were more common because of the amount of business and trade done there. Now the seer closed his words by saying that each one will find his reparation through the sin he himself committed, and by fixing his crookedness he will return to his place.

Zion shall be redeemed, etc. Zion will, in consequence of her justice, be redeemed out of the hand of Sennacherib.
