קוּמִי אוֹרִי כִּי בָא אוֹרֵךְ וּכְבוֹד ה’ עָלַיִךְ זָרָח
Arise, shine, for your light has come and the glory of G-d has shined upon you.
This haftarah has many positive prophecies: nations will go by your light, you will be radiant, caravans will come to you, etc. But who is the “you” being addressed? The Radak informs us that the prophecy is being addressed to Jerusalem.
