1 Chronicles 12:19-29

19 Some of the men of Manas'seh deserted to David when he came with the Philistines for the battle against Saul. (Yet he did not help them, for the rulers of the Philistines took counsel and sent him away, saying, "At peril to our heads he will desert to his master Saul.")
20 As he went to Ziklag these men of Manas'seh deserted to him: Adnah, Joz'abad, Jedi'a-el, Michael, Joz'abad, Eli'hu, and Zil'lethai, chiefs of thousands in Manas'seh.
21 They helped David against the band of raiders; for they were all mighty men of valor, and were commanders in the army.
22 For from day to day men kept coming to David to help him, until there was a great army, like an army of God.
23 These are the numbers of the divisions of the armed troops, who came to David in Hebron, to turn the kingdom of Saul over to him, according to the word of the LORD.
24 The men of Judah bearing shield and spear were six thousand eight hundred armed troops.
25 Of the Simeonites, mighty men of valor for war, seven thousand one hundred.
26 Of the Levites four thousand six hundred.
27 The prince Jehoi'ada, of the house of Aaron, and with him three thousand seven hundred.
28 Zadok, a young man mighty in valor, and twenty-two commanders from his own father's house.
29 Of the Benjaminites, the kinsmen of Saul, three thousand, of whom the majority had hitherto kept their allegiance to the house of Saul.
