Sha'arei Teshuvah (Gates of Repentance) is one of three works, along with Iggeret ha-Teshuvah ‎and Sefer HaYirah, that belong to the standard Jewish ethical works of the Middle Ages. It was written by Rabbeinu Yonah Gerondi, reportedly to atone for his ‎earlier attacks on Maimonides and to emphasize his repentance.‎
