It happened on the seventh day, that they said to Samson's wife, Entice your husband, that he may declare to us the riddle, lest we burn you and your father's house with fire: have you called us to impoverish us? is it not [so]?
And so Samson said to these thirty Philistines, I'm gonna give you a riddle: and if you can tell me the riddle by the time of the wedding day, then I will give you thirty shirts and thirty changes of garments: But if you can't tell me the riddle at the end of the seven days, then you gotta give me thirty shirts and thirty changes of garments ( Judges 14:12-13 ).
