1 Samuel 22:1-2

1 And David departed from there and escaped to the cave Adullam; and when his brethren and all his father's house heard [it], they went down there to him.

2 And every one [that was] in distress and every one that [was] in debt and all whose souls were bitter gathered themselves unto him, and he became the captain over them, and there were about four hundred men with him.
