1 Samuel 22:1-2

1 David therefore departed from there, and escaped to the cave of Adullam. And when his brothers and all his father's house heard it, they went down there to him.

2 And every man who was in distress, and every man who was in debt, and every man who was discontented, gathered themselves to him, and he became captain over them. And there were with him about four hundred men.
