David left Gath and escaped to Adullam's fortress. When David's siblings and all his extended family learned of this, they went to join him there.
Everyone who was in trouble, in debt, or in desperate circumstances gathered around David, and he became their leader. Approximately four hundred men joined him.
From there David went to Mizpeh in Moab. He said to the Moabite king, "Please let my father and mother stay with you until I know what God will do to me."
So David left his parents with the Moabite king, and they stayed with him the whole time David was in the fortress.
Then the prophet Gad told David, "Don't stay in the fortress any longer. Leave now and go to the land of Judah." So David left and went to Hereth forest.
