1 Samuel 25:20-22

As she was riding her donkey into a mountain ravine, she saw David and his men coming toward her. David had just been saying, “A lot of good it did to help this fellow. We protected his flocks in the wilderness, and nothing he owned was lost or stolen. But he has repaid me evil for good. May God strike me and kill me if even one man of his household is still alive tomorrow morning!”
