Shiza

Shiza is named once in scripture, as the father of one of David's mighty men. He belongs to the tribe of Reuben, and his son Adina serves among the chiefs east of the Jordan.

A Reubenite father

The roster of David's warriors records his son Adina among the leaders drawn from Reuben:

Adina the son of Shiza the Reubenite, a chief of the Reubenites, and thirty with him, (1Ch 11:42)

Nothing else is reported about Shiza himself. The verse fixes him only as the parent of a Reubenite chief who commanded a body of thirty under David.
