1 Chronicles 12:19-22

19Some of the men of Manasseh 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.")

20As he went to Ziklag, these men of Manasseh deserted to him: Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu, and Zillethai, chiefs of thousands in Manasseh.

21They helped David against the band of raiders, for they were all mighty men of valor and were commanders in the army.

22For from day to day men came to David to help him, until there was a great army, like an army of God.
