1 Samuel 29:9-11

Achish answered, “I know you are as good as an angel from God. But the Philistine commanders have said, ‘David must not go with us into battle.’ Early in the morning you and your master’s servants should leave. Get up as soon as it is light and go.” So David and his men got up early in the morning and went back to the country of the Philistines. And the Philistines went up to Jezreel.
