2 Samuel 2:3

And every one that was in distress, and every one that was in debt, and every one that was discontented, gathered themselves unto him; and he became a captain over them: and there were with him about four hundred men.

And David arose, and he passed over with the six hundred men that were with him unto Achish, the son of Maoch, king of Gath.

And it came to pass, when David and his men were come to Ziklag on the third day, that the Amalekites had invaded the south, and Ziklag, and smitten Ziklag, and burned it with fire;

Now these are they that came to David to Ziklag, while he yet kept himself close because of Saul the son of Kish: and they were among the mighty men, helpers of the war. They were armed with bows, and could use both the right hand and the left in hurling stones and shooting arrows out of a bow, even of Saul's brethren of Benjamin. The chief was Ahiezer, then Joash, the sons of Shemaah the Gibeathite; and Jeziel, and Pelet, the sons of Azmaveth; and Berachah, and Jehu the Antothite. And Ismaiah the Gibeonite, a mighty man among the thirty, and over the thirty; and Jeremiah, and Jahaziel, and Johanan, and Josabad the Gederathite, Eluzai, and Jerimoth, and Bealiah, and Shemariah, and Shephatiah the Haruphite, Elkanah, and Jesiah, and Azareel, and Joezer, and Jashobeam, the Korhites, And Joelah, and Zebadiah, the sons of Jeroham of Gedor.
