Judges 14:12-13

12Samson said to them, ‘Listen to this clever question. Try to give me an answer before my party finishes in seven days. If you answer the question, I will give you 30 linen shirts and 30 sets of clothes.

13But if you cannot tell me the answer, you will give me 30 linen shirts and 30 sets of clothes.’ The young men said, ‘Tell us your question.’
