Rabbi Pinchas b. Yair

R. Pinchas was the son-in-law of R. Shimon bar Yochai and lived during the time of R. Yehudah haNasi. He was most famous for his outstanding piety, especially in the area of tithes, such that even his donkey was stringent about them. He is also well known for his ladder of virtues, later immortalized by R. Moshe Hayyim Luzzatto.
