What does Judges 14:13 mean?

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

When they saw him, they brought thirty companions to be with him.

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;

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.

On the seventh day, they said to Samson’s wife, “Entice your husband, that he may declare to us the riddle, lest we burn you and your father’s house with fire. Have you called us to impoverish us? Isn’t that so?”

Samson’s wife wept before him, and said, “You just hate me, and don’t love me. You’ve told a riddle to the children of my people, and haven’t told it to me.” He said to her, “Behold, I haven’t told my father or my mother, so why should I tell you?”
