Judges 14:16-17

16So Samson’s wife wept before him and said, “You only hate me, you do not love me; you have asked my countrymen a riddle, and have not told [the answer] to me.” And he said to her, “Listen, I have not told my father or my mother [either], so [why] should I tell you?”

17However Samson’s wife wept before him seven days while their [wedding] feast lasted, and on the seventh day he told her because she pressed him so hard. Then she told the [answer to the] riddle to her countrymen.
