1 Samuel 27:1

New King James Version

David Allied with the Philistines

27 And David said in his heart, “Now I shall perish someday by the hand of Saul. There is nothing better for me than that I should speedily escape to the land of the Philistines; and Saul will ^[a]despair of me, to seek me anymore in any part of Israel. So I shall escape out of his hand.”
