Dan.12:1 And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.

Prince= rs sar, sar a head person (of any rank or class):–captain (that had rule), chief (captain), general, governor, keeper, lord, ((-task- ))master, prince(-ipal), ruler, steward.

And so in
Dan.10:20 the word says..”Then said he, Knowest thou wherefore I come unto thee? and now will I return to fight with the prince of Persia: and when I am gone forth, lo, the prince of Grecia shall come.
21 But I will shew thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince”.

Vs. 20. To fight with the king of Persia] What was the fight? It was merely to remove all the doubts of Cyrus, and to excite him to do all that God designs him to do for the restoration of my people, the Jews, and the rebuilding of the city and temple of Jerusalem. Nothing less than a supernatural agency in the mind of Cyrus can account for his decree in favour of the Jews. He had no natural, no political inclination to it; and his reluctance to obey the heavenly motions is here represented as a fight between him and the angel.

The prince of Grecia shall come.] refers to Alexander the Great, who was to destroy the Persian empire later on.

Before dealing with Jude 9, let us qickly deal wih the issue of Rev 12:7,

7 “And there was war in heaven: Michael and his angels fought against the dragon; and the dragon fought and his angels”.

There was war in heaven] If you take time to study the Rabbical write ups, you will clearly see that this is dealing with the same concept of what happened in Ex 14:7-24,.

“ And he took six hundred chosen chariots, and all the chariots of Egypt, and captains over every one of them….. 27 And Moses stretched forth his hand over the sea, and the sea returned to his strength when the morning appeared; and the Egyptians fled against it; and the LORD overthrew the Egyptians in the midst of the sea”

It is evident that the man child of Rev 12 speaks historically of the church that was born during the Roman Empire .We know this, because when Jesus was comforting the disciples with the Promise of the Holy spirit he told them ..

John.16: 20 Verily, verily, I say unto you, That ye shall weep and lament, but the world shall rejoice: and ye shall be sorrowful, but your sorrow shall be turned into joy.
21 A woman when she is in travail hath sorrow, because her hour is come: but as soon as she is delivered of the child, she remembereth no more the anguish, for joy that a man is born into the world.
22 And ye now therefore have sorrow: but I will see you again, and your heart shall rejoice, and your joy no man taketh from you.

So the release of the Holy Ghost on the day of Pentecost gave birth to the man-child , “ that a man is born into the world “

Just like the Church was his first born in Egypt. Even so the man child, during the Roman Empire.

“There was war among those above and among those below, and there was great war in heaven.”

Again, in Verse. 7. And there was war in heaven] The war in heaven in here was simply an allusion to the throne of the Roman empire, the consequent of which was the breaking out of civil commotions among the governors of this empire.

“Michael and his angels fought against the dragon”

Michael was the man child , being the Christ in the midst of his people which the woman brought forth, as is evident from the context, was therefore, the dynasty of Christian Roman emperors. This dynasty is represented by Michael, because he is “the great prince which standeth for the children of God’s people.” As seen in Da 12:1.

“And the dragon fought and his angels” here then are his ministers.

Now in Jude 1:9 “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”.

First look at
Zec.3: 1 ¶ And he shewed me Joshua the high priest standing before the angel of the LORD, and Satan standing at his right hand to resist him.
2 And the LORD said unto Satan, The LORD rebuke thee, O Satan; even the LORD that hath chosen Jerusalem rebuke thee: is not this a brand plucked out of the fire?
3 Now Joshua was clothed with filthy garments, and stood before the angel.
4 And he answered and spake unto those that stood before him, saying, Take away the filthy garments from him”

Verse 1. And he showed me Joshua the high priest] The Angel of the Lord is the Messiah, as we have seen before; Joshua, the high priest, here represent the whole Jewish people; and Satan, the grand accuser of the brethren. What the subject of dispute was, we perhaps learn from Jude 1:9. Michael and Satan disputed about the body of Moses. This could not refer to the natural body of the Jewish lawgiver, which had been dead about one thousand years; it must therefore refer to that body of laws given to the Jews by Moses, for the breach of which Satan, who was their tempter to disobedience, now comes forward as their accuser; that, exciting the justice of God against them, they may be all brought to perdition.

There is a play on words here:-

Satan standing at his right hand to resist him.] Njs Satan signifies an adversary. wnjsl lesiteno, to be his adversary, or accuser.

Verse 3. Joshua was clothed with filthy garments] Here the Jewish people were in a most forlorn, destitute, and to all human appearance despicable, condition; and besides all, they were sinful, and the priesthood defiled by idolatry; and nothing but the mercy of God could save them.

Zec 3:1, to have stood, Satan being at his right hand to resist him, namely, in his plan of restoring the Jewish Church and state, called by Jude the body of Moses, just as the Christian Church is called by Paul the body of Christ.

Then compared with .. Jude 1:9 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”

Disputed about the body of Moses.

There is no evident in scriptures as to the source of St. Jude’s statement. Meaning he drew it from the source of some tradition among his countrymen. Just as one can see from the work of Debarim Rabba, sec. ii., fol. 263, 1:

A similar contention story of Michael with Satan is mentioned in Yalcut Rubeni, fol. 43, 3: “At the time in which Isaac was bound there was a contention between Michael and Satan. Michael brought a ram, that Isaac might be liberated; but Satan endeavoured to carry off the ram, that Isaac might be slain.”

So evidently Jude picked his source from tradition
Now note it , that the contention mentioned by Jude is not about the sacrifice of Isaac, nor the soul of Moses, but about the BODY OF MOSES;.

Some think the devil wished to show the Israelites where Moses was buried, knowing that they would then adore his body; and that Michael was sent to resist this discovery.

As so we read in Deut.34: 5 “So Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD.
6 And he buried him in a valley in the land of Moab, over against Bethpeor: but no man knoweth of his sepulchre unto this day”.

Then from where was the devil dragging the body of Moses and with whom? The very God who buried him all by himself and no man knew?

As we have stated before, Jude’s write up were tied to earlier Jewish fables, but of course you must read the scriptures with a spiritual mind

The Body of Christ is the church, just as the Body of Moses was the church in the wilderness. What ruled the Body of Moses was the law, while the Body of Christ is ruled by the law of the Spirit of Christ.

What the devil was contending with was that Christ will not go to the Cross so that the power of the law which is sin that results in death might continue. In other words, the devil does not want the law to be abolished as speaking of the Body of Moses.

And this is defined for us in
1 Cor.15: 54 “So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
55 O death, where is thy sting? O grave, where is thy victory? {grave: o
56 The sting of death is sin; and the strength of sin is the law”.

Michael the Archangel.

Jude 9. “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”.

So when we read of [ Yet Michael the archangel] With regards to Michael in the Bible , in the words of “Rabbi Judah Hakkodesh : “Wherever Michael is said to appear, the glory of the Divine Majesty is always to be understood.” Just like
Shemoth Rabba, in sec. ii., fol. 104, 3. So every one of those writers have always considered Michael as we must see to be the Messiah manifested in the flesh. Nothing more.

May we not forget this fact, that the word archangel is never found in the plural number in the sacred writings. Therefore there is properly only one archangel, one chief or head of the entire angelic host.

Just like the word Devil when used for Satan is never used in the plural sense .It is but one, the father of lies .John.8:44.

Michael is this archangel, and head of all the angelic orders; the devil, great dragon, or Satan, is head of all the diabolic orders.

When these two hosts are opposed to each other they are said to act under these two chiefs, as leaders; hence in Re 12:7, it is said: MICHAEL and his angels fought against the DRAGON and his angels.

The word Michael lakym, is the compounded of ym mi, who, k ke, like, and la El, God; he who is like God; hence by this personage, even in the Apocalypse, many understood Him to be the Lord Jesus. There can be no doubt about this.

Therefore Archangel Michael, the Prince of the Jewish people is no other person but Jesus Christ the Lord.
