Judges 14:12-13

Then Samson said to them, “Let me pose a riddle to you. If you can correctly solve and explain it to me within the seven days of the feast, then I will give you thirty linen garments and thirty changes of clothing. But if you cannot explain it to me, then you shall give me thirty linen garments and thirty changes of clothing.” And they said to him, “Pose your riddle, that we may hear it.”
