Rashi on Isaiah
and they leaned on the God of Israel in the days of Hezekiah, about whom it is written (2 Kings 18:5): “He trusted in the Lord God of Israel.” That caused them not to be exiled except in the days of Nebuchadnezzar, who exiled them to Babylon, and they had a redemption through Cyrus.
Ibn Ezra on Isaiah
For they call themselves of the holy city, namely children of Zion.
Ibn Ezra on Isaiah
And stay themselves upon the God of Israel with their lips.
