'Defected' in the Bible

From Manasseh also some defected to David when he was about to go to battle with the Philistines against Saul. But they did not help them, for the lords of the Philistines after consultation sent him away, saying, “At the cost of our heads he may defect to his master Saul.”

As he went to Ziklag there defected to him from Manasseh: Adnah, Jozabad, Jediael, Michael, Jozabad, Elihu and Zillethai, captains of thousands who belonged to Manasseh.
