1 Samuel 22:2-4

New Century Version

² Everyone who was in trouble, or who owed money, or who was unsatisfied gathered around David, and he became their leader. About four hundred men were with him.

³ From there David went to Mizpah in Moab and spoke to the king of Moab. He said, “Please let my father and mother come and stay with you until I learn what God is going to do for me.” ⁴ So he left them with the king of Moab, and they stayed with him as long as David was hiding in the stronghold.
