Jude tells us that Michael was sent by God to deal in some way with the body of Moses, which God Himself had buried after Moses’ death (
Deuteronomy 34:5-6). Various theories have been put forth as to what this struggle over Moses’ body was about. One is that Satan, ever the accuser of God’s people (
Revelation 12:10), may have resisted the raising of Moses to eternal life on the grounds of Moses’ sin at Meribah (
Deuteronomy 32:51) and his murder of the Egyptian (
Exodus 2:12). I believe it was over the resurrection of Moses. Why else is Michael and Satan disputing about the body of Moses?
As far as the preeminence of Yeshua's resurrection from the dead, it is via promise that those who were resurrected before His resurrection were by promise, and so also are we by that same promise which is now fact. He, who knows beginning from end, did choose to take Enoch, Elijah, and Moses to heaven. The visitation with Yeshua on the Mount of transfiguration should not be considered a "vision", for our Lord worked in concrete reality and not figments of promises. Moses and Elijah visits were a great comfort, to shore up and reconfirm our Lord in His purpose.
