Judges 14:15-16

15On the fourth day they said to Samson's wife, "Entice your husband to tell us what the riddle is, lest we burn you and your father's house with fire. Have you invited us here to impoverish us?"

16And Samson's wife wept over him and said, "You only hate me; you do not love me. You have put a riddle to my people, and you have not told me what it is." And he said to her, "Behold, I have not told my father nor my mother, and shall I tell you?"
