1 Chronicles 12:19; 1 Chronicles 12:22

19 Some 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.”)

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