1 Samuel 22:2-3 NIV
All those who were in distress or in debt or discontented gathered around him, and he became their commander. About four hundred men were with him.
From there David went to Mizpah in Moab and said to the king of Moab, “Would you let my father and mother come and stay with you until I learn what God will do for me?”
