1 Samuel 22:1-3

1 David therefore departed thence, and escaped to the cave Adullam: and when his brethren and all his father’s house heard it , they went down thither to him.

2 And every one that was in distress, and every one that was in debt, and every one that was discontented, gathered themselves unto him; and he became a captain over them: and there were with him about four hundred men.

3 And David went thence to Mizpeh of Moab: and he said unto the king of Moab, Let my father and my mother, I pray thee, come forth, and be with you, till I know what God will do for me.
