Judges 14:10-14 (KJV)

10 So his father went down unto the woman: and Samson made there a feast; for so used the young men to do. 11 And it came to pass, when they saw him, that they brought thirty companions to be with him. 12 And Samson said unto them, I will now put forth a riddle unto you: if ye can certainly declare it me within the seven days of the feast, and find it out, then I will give you thirty sheets and thirty change of garments: 13 But if ye cannot declare it me, then shall ye give me thirty sheets and thirty change of garments. And they said unto him, Put forth thy riddle, that we may hear it.

14 And he said unto them, Out of the eater came forth meat, and out of the strong came forth sweetness. And they could not in three days expound the riddle.
