1 Chronicles 12:19; 1 Chronicles 12:22

19 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."

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