1 Samuel 30:14-16

14We raided the Negev of the Cherethites, the territory of Judah, and the Negev of Caleb, and we burned down Ziklag.”

15“Will you lead me to these raiders?” David asked.

And the man replied, “Swear to me by God that you will not kill me or deliver me into the hand of my master, and I will lead you to them.”

16So he led David down, and there were the Amalekites spread out over all the land, eating, drinking, and celebrating the great amount of plunder they had taken from the land of the Philistines and the land of Judah.
