1 Samuel 22:8
Is that why all of you have conspired against me? Not one of you told me that my own son had made a covenant with the son of Jesse. Not one of you has shown concern for me or revealed to me that my son has stirred up my own servant to lie in wait against me, as is the case today."

1 Samuel 23:18
