1 Samuel 22:2-4
1 Samuel 22: 2 to 4
2 Anyone who was in distress, anyone in debt, and anyone embittered rallied around him, and he became their leader. There were about 400 men with him.
3 Then David left from there to Mizpah of Moab, and he said to the king of Moab, “Please, let my father and my mother come and stay with you until I know what God will do for me.”
4 Then he brought them to the king of Moab, and they stayed with him all the time that David was in the stronghold.
