The poetry of the synagogue is furthermore deeply indebted to Bonfils for the introduction of the piyyuṭim into the prayers, in face of great opposition. Of his many piyyuṭim, the best-known is that written for "Shabbat HaGadol" (the Sabbath before Passover), beginning with the words "Elohei haruchot," and containing the rules for the Passover-cleaning ("bi'ur") and the narrative service for the evening.
The synagogue's poetic repertoire is also heavily reliant on Bonfils' contribution of piyyuṭim to the prayers, despite facing considerable opposition. Notably, his work for "Shabbat HaGadol" (the Sabbath before Passover) sets forth rules for Passover-cleaning ("bi'ur") and a narrative service for the evening.
