The Classic commentary of Rabbeinu Yonah on Tractate Avos is finally available for the English reader in a beautiful new edition

Rabbeinu Yonah, a name that evokes awe and reverence among Jews the
world over, was one of the greatest Talmudic scholars and ethical
personalities in Jewish history. He was the teacher of the Rashba (Rabbi
Shlomo ben Aderet) and is quoted several times in the Tosafos
commentary on the Talmud. His ethical works, Sha’arei Teshuvah and Sefer
HaYirah, have inspired countless Jews throughout the centuries.

Although commentaries on Pirkei Avos abound, Rabbeinu Yonah’s is one of
the most popular and oft-quoted. Until now, it had gone untranslated,
but that omission has now been rectified. Let Rabbeinu Yonah reveal the
profound wisdom of our Sages, and be uplifted and transformed. This
volume is a precious gift from a beloved teacher to the Jewish people,
and it belongs in every Jewish home.
