What does Judges 14:11 mean?

After a while he returned to take her; and he went over to see the carcass of the lion; and behold, there was a swarm of bees in the body of the lion, and honey.

He took it into his hands, and went on, eating as he went. He came to his father and mother, and gave to them, and they ate, but he didn’t tell them that he had taken the honey out of the lion’s body.

His father went down to the woman; and Samson made a feast there, for the young men used to do so.

Samson said to them, “Let me tell you a riddle now. If you can declare it to me within the seven days of the feast, and find it out, then I will give you thirty linen garments and thirty changes of clothing;

but if you can’t declare it to me, then you shall give me thirty linen garments and thirty changes of clothing.” They said to him, “Tell us your riddle, that we may hear it.”

He said to them, “Out of the eater came out food. Out of the strong came out sweetness.” They couldn’t in three days declare the riddle.
