1 Chronicles 12:19-22

19Some of the tribe of Manasseh defected to David when he went with the Philistines to fight against Saul. (He and his men did not help the Philistines because, after consultation, their rulers sent him away. They said, “It will cost us our heads if he deserts to his master Saul.”)

20When David went to Ziklag, these were the men of Manasseh who defected to him: Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu and Zillethai, leaders of units of a thousand in Manasseh.

21They helped David against raiding bands, for all of them were brave warriors, and they were commanders in his army.

22Day after day men came to help David, until he had a great army, like the army of God.
