און עס װעט זײַן, דער װאָס איז געבליבן אין צִיון, און דער װאָס האָט זיך אָפּגעשטעלט אין ירושלים, װעט ״הײליקער״ געזאָגט װערן צו אים –איטלעכער װאָס איז פֿאַרשריבן צום לעבן אין ירושלים;
Rashi
And it shall come to pass, that every survivor among them will settle in Zion.
Ibn Ezra
That is written, etc. I shall explain this in the minor prophets (Mal. 3:16).3The words referred to are כתוב בשמים מכתב לא ימחק, What is written by God is a writing which can never be erased. It is a figurative expression for: it is quite sure, it is immutable.
Rashi
“holy” shall be said of him All of them will be righteous. Now lest you say that the righteous who died prior to this day have lost their honor, the Scripture states: “anyone inscribed for life,” in the Hereafter, will be in Jerusalem.In this manner, Jonathan translates it.
