Judges 14:12-13

12And Samson said unto them, Let me now put forth a riddle unto you: if ye can declare it unto me within the seven days of the feast, and find it out, then I will give you thirty linen garments and thirty changes of raiment; 13but if ye cannot declare it unto me, then shall ye give me thirty linen garments and thirty changes of raiment. And they said unto him, Put forth thy riddle, that we may hear it.
