Pinchas ben Yair

Pinchas ben Yair (Hebrew: פנחס בן יאיר) was a Tanna of the 4th generation who lived, probably at Lod, in the late 2nd century. He was the father-in-law of Shimon bar Yochai and a fellow disciple of Judah haNasi. He was more celebrated for piety than for learning, although his discussions with his son-in-law demonstrate great sagacity and a profound knowledge of tradition.
