'Solve' in the Bible

Samson said to them, "I will give you a riddle. If you really can solve it during the seven days the party lasts, I will give you thirty linen robes and thirty sets of clothes.

But if you cannot solve it, you will give me thirty linen robes and thirty sets of clothes." They said to him, "Let us hear your riddle."

He said to them, "Out of the one who eats came something to eat; out of the strong one came something sweet." They could not solve the riddle for three days.
