1 Chronicles 12:19-22

Some men from Manasseh defected from the Israelite army and joined David when he set out with the Philistines to fight against Saul. But as it turned out, the Philistine rulers refused to let David and his men go with them. After much discussion, they sent them back, for they said, “It will cost us our heads if David switches loyalties to Saul and turns against us.” Here is a list of the men from Manasseh who defected to David as he was returning to Ziklag: Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu, and Zillethai. Each commanded 1,000 troops from the tribe of Manasseh. They helped David chase down bands of raiders, for they were all brave and able warriors who became commanders in his army. Day after day more men joined David until he had a great army, like the army of God.
