Biography
Rabbi Yakim Ish Chadid was a tanna of the second generation whose name is brought a single time in the Mishnah. His appellation points to where he came from — Chadid, a town of the Shefelah, the lowland country of Eretz Yisrael.
Together with Rabbi Yehoshua ben Chananya he gave testimony at Yavneh concerning a halacha, and that testimony is the one place his name is preserved.
רבי יקים איש חדיד היה תנא בדור השני, אשר נזכר פעם אחת במשנה. מוצאו של רבי יקים, על פי שמו, הוא העיר חדיד שבשפלה.
