What are the halachic guidelines for behavior during Chazarat Hashatz? May one learn during Chazarat Hashatz?Those who are meticulous to fulfill the mitzvah of wearing both Tefillin of Rashi and Tefillin of Rabbenu Tam should be careful not to remove their Rashi Tefillin and put on the Rabbenu Tam Tefillin during Chazarat Hashatz. [1] This is because Chazarat Hashatz requires complete attention and participation, and any form of distraction or interruption even for a mitzvah.

Does one sit or stand during Chazarat HaShatz? There are differing halachic opinions regarding whether one must stand during Chazarat HaShatz. Most Ashkenazic poskim encourage standing throughout the repetition. Among Sephardim, the widespread custom is to sit during Chazarat HaShatz; however, it is considered praiseworthy to stand.

When the Shaliach Tzibbur recites the Chazarat HaShatz, the congregation is obligated to listen attentively and respond with "Amen" at the conclusion of each beracha. This communal response is not merely ceremonial; it is an essential part of the tefillah. If there is no minyan of individuals responding "Amen," the berachot recited by the Shaliach Tzibbur may be considered close to berachot levatalah, blessings said in vain.

Why do we say "Hashem, sefatai tiftach u’fi yagid tehilatecha" before Shemoneh Esrei? The verse “Hashem, sefatai tiftach u’fi yagid tehilatecha” (“Hashem, open my lips, and my mouth will declare Your praise” – Tehillim 51:17) was instituted to be said immediately before beginning the Shemoneh Esrei. This pasuk serves not only as a beautiful introduction, asking Hashem to help us speak His praise properly, but also carries a deeper meaning.
