The words of Hashivenu come from the last verses of Megilat Eikha (Lamentations 5:21), which we also sing when we return the Sefer Torah to the Ark: “Bring us back to You, HaShem, and we will return; renew our days as of old.” Here it is by Hanan Ben Ari.
הֲשִׁיבֵ֨נוּ ה׳ ׀ אֵלֶ֙יךָ֙ וְֽנָשׁ֔וּבָה חַדֵּ֥שׁ יָמֵ֖ינוּ כְּקֶֽדֶם
