Isaías 27:3 Comentario: Rashi & Ibn Ezra

I, the Lord, guard it in the time of exile.

I, the Lord, do keep it, that is to say, the Divine glory remains in Zion.

every moment I water it Little by little I water it with the cup of retribution that comes upon it, lest I visit upon it at once and I destroy it. Therefore, night and day I ponder about it. Jonathan renders: Were it not that I visit upon them the iniquities that they are accustomed to commit before Me, I would guard it day and night.
