Adina

Adina (meaning slender or delicate) was a son of Shiza the Reubenite and one of David's thirty heroes — the second tier of his elite military corps below the Three. He is listed in 1 Chronicles 11:42 as having thirty men under his command, suggesting he held a position of some leadership within David's standing army during the consolidation of the kingdom. His Reubenite tribal identity is specifically noted, reflecting the participation of the eastern tribes in David's military organization.

Beyond his listing in the roster of David's mighty men, Adina receives no individual narrative in Scripture. His inclusion among the heroes who formed the core of David's military strength places him in the early monarchic period, likely during the years when David was establishing his kingdom from Hebron and then Jerusalem.
