בַּיּ֣וֹם הַה֗וּא יִֽהְיֶה֙ צֶ֣מַח יְהוָ֔ה לִצְבִ֖י וּלְכָב֑וֹד וּפְרִ֤י הָאָ֙רֶץ֙ לְגָא֣וֹן וּלְתִפְאֶ֔רֶת לִפְלֵיטַ֖ת יִשְׂרָאֵֽל׃
Rashi on Isaiah
On that day After the beauty of the ornaments of the adulteresses and the wanton women is curtailed, the glory of My people and the beauty of their honor will no longer depend upon these things.
Ibn Ezra on Isaiah
The branch of the Lord. Some refer this to Hezekiah; I think that it signifies the righteous portions of the inhabitants of Jerusalem that will be saved.
