Judges 14:13 (KJV)

And it came to pass, when they saw him, that they brought thirty companions to be with him.

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:

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.

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.

And it came to pass on the seventh day, that they said unto Samson’s wife, Entice thy husband, that he may declare unto us the riddle, lest we burn thee and thy father’s house with fire: have ye called us to take that we have? is it not so?
