Why was the Angel Michael fighting the Devil for Moses' body?

I get this from the book of Jude. I know the meaning of the chapter as a whole it's just that this verse stuck out. Does anyone have a clue on this event? Here is the verse for reference. >Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee. [Jde 1:9 KJV]
