1. A Gershonite Levite, son of Jahath. 1 Chronicles 6:20. (B.C. after 1706).

2. Another Gershonite, son of Shimei, 1 Chronicles 6:42, possibly the same as Zimmah, 1.

3. Father or ancestor of Joab, a Gershonite, in the reign of Hezekiah. 2 Chronicles 29:12. (B.C. before 726). At a much earlier period, we find the same collocation of names, Zimmah and Joah as father and son. 1 Chronicles 6:20.
