This has always struck me as a very interesting passage. We are taught that the tongue is small but hard to control but control it we must, never to use the Lord's name in vain, blaspheme, lie, gossip, slander, and so forth and even avoid accusations against powers ordained by God.

Rom. 13:1 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God

Henry: As to the contest about the body of Moses, it appears that Satan wished to make the place of his burial known to the Israelites, in order to tempt them to worship him, but he was prevented, and vented his rage in desperate blasphemy. This should remind all who dispute never to bring railing charges. Also learn hence, that we ought to defend those whom God owns.
