1 Samuel 27:11-12

Amplified Bible

¹¹ David did not leave a man or a woman alive to bring news to Gath, saying [to himself], “Otherwise they will tell about us, saying, ‘This is what David has done, and this has been his practice all the time that he has lived in the country of the Philistines.’” ¹² Achish believed David, saying, “He has certainly become hated by his people in Israel; so he will always be my servant.”
