What is the source of the popular song Od Yeshama?
I tried searching for "עוד ישמע בְּעָרֵי יְהוּדָה וּבְחֻצוֹת" and did not find anything.
I am asking because I was wondering if it should be pronounced יְרוּשָׁלִַם or יְרוּשָׁלִַים? I was surprised that typing either into google did not yield the Posuk. I am now curious about the source for the song and the proper pronunciation.
