Is there biblical reference to Michael, the archangel’s role and being? I am looking for the biblical references to Michael the angel ? And what are/were his/her role? There are some christian groups that attributes  Michael same with Jesus. Is there any biblical reference to it?
Well, Jude 9 says:


  But Michael the archangel, when he disputed with the devil and argued about the body of Moses, did not dare pronounce against him a railing judgment, but said, "The Lord rebuke you!"


From that verse, it would seem to be hard to equate Michael and Jesus. 

The only other reference to "archangel" I know of is in 1 Thessalonians 4:16:


  For the Lord Himself will descend from heaven with a shout, with the voice of the archangel and with the trumpet of God, and the dead in Christ will rise first.


That verse seems to indicate the "voice of the archangel" will announce Christ's (
the Lord Himself) return - again listed as a separate being.
