1 Samuel 29:8

“But what have I done?” said David. “Have you had a single cause for complaint from the day I joined up with you until now? Why can’t I fight against the enemies of my master the king?”

^9-10 “I agree,” said Achish. “You’re a good man—as far as I’m concerned, God’s angel! But the Philistine officers were emphatic: ‘He’s not to go with us into battle.’ So get an early start, you and the men who came with you. As soon as you have light enough to travel, go.”
