1 Samuel 29:4

And the captains of the Philistines were displeased at him, and they say to him, Send the man away, and let him return to his place, where thou didst set him; and let him not come with us to the war, and let him not be a traitor in the camp: and wherewith will he be reconciled to his master? will it not be with the heads of those men?
