1 Chronicles 12:19-22

19And some from Manasseh defected to David when he was going with the Philistines to battle against Saul; but they did not help them, for the lords of the Philistines sent him away by agreement, saying, “He may defect to his master Saul and endanger our heads.”

20When he went to Ziklag, those of Manasseh who defected to him were Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu, and Zillethai, captains of the thousands who were from Manasseh.

21And they helped David against the bands of raiders, for they were all mighty men of valor, and they were captains in the army.

22For at that time they came to David day by day to help him, until it was a great army, like the army of God.
