1 Samuel 30:15

““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.””

“And David said to him, Canst thou bring me down to this company? And he said, Swear unto me by God, that thou wilt neither kill me, nor deliver me into the hands of my master, and I will bring thee down to this company.”

“And 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.”

“And David saith unto him, `Dost thou bring me down unto this troop?' and he saith, `Swear to me by God--thou dost not put me to death, nor dost thou shut me up into the hand of my lord--and I bring thee down unto this troop.'”
