“If I forget you, O Yerushalayim, let my right hand wither” PSALMS 137:5 (The Israel Bible™)
Psalm 137 was written by the rivers of Babylon, where the exiled Jews wailed and lamented the destruction of the Beit Hamikdash. They wondered how they would continue to endure on foreign soil. How could they continue to sing the songs of Hashem, which were supposed to be sung in the Temple, in the exile? Their answer was an oath to never forget Yerushalayim. This psalm makes an oblique reference to Sefer Devarim 8:19, “If you do forget Hashem your God and follow other gods to serve them or bow down to them, I warn you this day that you shall certainly perish.” Israel’s exile came when they forgot God in their land. In Babylon, they promised themselves never to repeat that mistake, and never to forget Yerushalayim. Today, this psalm is recited at Jewish weddings just before the groom breaks a glass, ensuring that Jerusalem is always at the forefront of our minds and reminding us that no joyous occasion is complete until Yerushalayim is restored to its former glory.
