'Changes' in the Bible

And Samson said unto them, Let me now put forth a riddle unto you: if ye can declare it unto me within the seven days of the feast, and find it out, then I will give you thirty linen garments and thirty changes of raiment;

but if ye cannot declare it unto me, then shall ye give me thirty linen garments and thirty changes of raiment. And they said unto him, Put forth thy riddle, that we may hear it.

And the Spirit of Jehovah came mightily upon him, and he went down to Ashkelon, and smote thirty men of them, and took their spoil, and gave the changes of raiment unto them that declared the riddle. And his anger was kindled, and he went up to his father's house.
