157. U’va l’Tziyon

25:3 We say the Kedusha in U’va l’Tziyon with its Aramaic paraphrase. We must take care to recite this with proper concentration, though the Aramaic paraphrase should be recited quietly. (When praying alone, it’s okay to say it out loud – Mishnah Brurah 132:4.)

25:4 One may not leave shul before the Kedusha in U’va l’Tziyon.
