This Thursday is תשעה באב, the saddest day of the year, when we commemorate the destruction of our spiritual home, the בית המקדש. It is a day of deep mourning, a pain expressed most acutely in פרק קלז of תהלים, commonly known as על נהרות בבל. The passage begins by describing the grief of the Jewish people in exile: “על־נהרות בבל שם ישבנו גם־בכינו בזכרנו את־ציון - On the rivers of Babylon - there we sat and also cried in remembering Zion”. They sit, mourn, and cry over what they have lost, hanging up their harps in sorrow. But this raises the question: Why? What are they mourning over? Why could they not simply start again? Yes, they were no longer in ירושלים, but couldn’t they still rebuild their lives and even thrive in בבל? What exactly had they lost? Later in the פרק, we encounter some of the most famous פסוקים in תהלים, the promise of: “אם־אשכחך ירושל͏ם תשכח ימיני. תדבק־לשוני לחכי אם־לא אזכרכי אם־לא אעלה את־ירושל͏ם על ראש שמחתי - If I forget you, Jerusalem, I shall forget my right hand. My tongue will cleave to my palate if I don’t remember you - if I don’t raise Jerusalem above my highest joy”. These פסוקים too require understanding: What are we swearing ourselves to? What does it mean to never forget ירושלים? The complexity only deepens when we reach the end of the chapter: “בת־בבל השדודה אשרי שישלם־לך את־גמולך שגמלת לנו - Daughter of Babylon, destined to be devastated, happy is he who repays for the dealings that you have done with us.” Suddenly the פרק switches from mourning ירושלים to a prophecy of retribution against בבל. This only raises more questions: How did we get here? What brings about this dynamic switch in themes? And ultimately, as a whole, what is this פרק meant to teach us? How are we to understand the promise of אם־אשכחך ירושל͏ם? How is it meant to shape our connection to ירושלים today?
