1 Samuel 22:1-5

So David got away and escaped to the Cave of Adullam. When his brothers and others associated with his family heard where he was, they came down and joined him. Not only that, but all who were down on their luck came around—losers and vagrants and misfits of all sorts. David became their leader. There were about four hundred in all. Then David went to Mizpah in Moab. He petitioned the king of Moab, “Grant asylum to my father and mother until I find out what God has planned for me.” David left his parents in the care of the king of Moab. They stayed there all through the time David was hiding out. The prophet Gad told David, “Don’t go back to the cave. Go to Judah.” David did what he told him. He went to the forest of Hereth.
