1 Samuel 29:6-7

So Achish had to send for David and tell him, “As GOD lives, you’ve been a trusty ally—excellent in all the ways you have worked with me, beyond reproach in the ways you have conducted yourself. But the warlords don’t see it that way. So it’s best that you leave peacefully, now. It’s not worth it, displeasing the Philistine warlords.”
