1 Samuel 30:14-16

14We made a raid upon the South of the Cherethites, and upon that which belongeth to Judah, and upon the South of Caleb; and we burned Ziklag with fire. 15And David said to him, Wilt thou bring me down to this troop? And he said, Swear unto me by God, that thou wilt neither kill me, nor deliver me up into the hands of my master, and I will bring thee down to this troop.

16And when he had brought him down, behold, they were spread abroad over all the ground, eating and drinking, and dancing, because of all the great spoil that they had taken out of the land of the Philistines, and out of the land of Judah.
