1 Samuel 29:4; 1 Samuel 29:10

4 But the Philistine commanders were angry with Achish and said, “Send the man back, that he may return to the place you assigned him. He must not go with us into battle, or he will turn against us during the fighting. How better could he regain his master’s favor than by taking the heads of our own men?

10 Now get up early, along with your master’s servants who have come with you, and leave in the morning as soon as it is light.”
