1 Chronicles 12:16-17

There were also men from the tribes of Benjamin and Judah who joined David in his wilderness fortress. When David went out to meet them, this is what he said: “If you have come in peace and to help me, you are most welcome to join this company; but if you have come to betray me to my enemies, innocent as I am, the God of our ancestors will see through you and bring judgment on you.”
