1 Chronicles 12:4

Ismaiah the Gibeonite. — Gibeon belonged to Benjamin (1 Chronicles 9:35), and 1 Chronicles 12:2 proves that Ismaiah was a Benjamite, not a Gibeonite in the strict sense of the term.

A mighty man among the thirty. — The “thirty” must be the famous corps (1 Chronicles 11:25). Ismaiah’s name does not occur in the catalogue, perhaps because he died before it was drawn up.

Over the thirty may mean that at one time he was captain of the band, or it may simply denote comparison — “a hero above the thirty.”

Josabad the Gederathite; of Gederah in the lowland of Judah (Joshua 15:36). Josabad is perhaps the same as Zabad ben Ahlai (1 Chronicles 11:41), one of the thirty.
