פּירוש אויף ישעיהו 48:2

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.

For they call themselves of the holy city, namely children of Zion.

And stay themselves upon the God of Israel with their lips.
