Jude

"Yet Michael the archangel, in contending with the devil, when he disputed about the body of Moses, dared not bring against him a reviling accusation, but said, 'The Lord rebuke you!'" v.9

Read Jude
Jude is one of Jesus' half brothers as we see he's brother of James who we know was another half brother of Jesus.  How cool that two of Jesus' half brothers were writers through the Holy Spirit of two New Testament letters!
Well we know of Michael the archangel from reading Daniel, but also it seems that the two named celestial angles in scripture are spoken of more than the hundreds of godly men and women in scripture.  We don't have a recorded account of Satan and Michael arguing about the body of Moses, Jude most likely learned this from revelation or ancient tradition. We can learn a bit more what this looked liked.  Why would the devil want Moses' physical dead body?  Perhaps it's not his physical body being spoken of but of something valuable to satan.  As we see from Numbers 11 "So the Lord said to Moses: “Gather to Me seventy men of the elders of Israel, whom you know to be the elders of the people and officers over them; bring them to the tabernacle of meeting, that they may stand there with you. 17 Then I will come down and talk with you there. I will take of the Spirit that is upon you and will put the same upon them; and they shall bear the burden of the people with you, that you may not bear it yourself alone."  We see this body of 70 elders who receive the same Spirit that was on Moses to help lead the people.  Body is the substance that makes up a thing, think of how we speak of body of hair for example or body of believers.  
What "body" of yours would be valuable to others after you die?
