Now Abishai the brother of Joab the son of Zeruiah [was] himself the leader of the thirty. He [was] wielding his spear against three hundred slain and {gained a name} among the thirty.

Among the Thirty were Joab's brother Asahel, Dodo's son Elhanan of Bethlehem,

He was the most honored of the Thirty, but he did not become one of the Three. David put him in charge of his bodyguard.

Again, David gathered together all the chosen men of Israel, thirty thousand.

David was thirty years old when he began to reign, and he reigned forty years.

In Hebron he reigned over Judah seven years and six months: and in Jerusalem he reigned thirty and three years over all Israel and Judah.

And three of the thirty chief men went down, and came to David in the harvest time unto the cave of Adullam: and the troop of the Philistines encamped in the valley of Rephaim.

Uriah the Hittite: thirty and seven in all.

He was most honored of the thirty, therefore he became their commander; however, he did not attain to the three.
