There has been a debate concerning the death of Moses, where he was buried, who buried him and where his grave is today. But luckily, the Bible is very clear about his death.
What does the Bible say?
Deuteronomy 34: 1-7 KJV
1 And Moses went up from the plains of Moab unto the mountain of Nebo, to the top of Pisgah, that is over against Jericho. And the LORD shewed him all the land of Gilead, unto Dan,
4 And the LORD said unto him, This is the land which I sware unto Abraham, unto Isaac, and unto Jacob, saying, I will give it unto thy seed: I have caused thee to see it with thine eyes, but thou shalt not go over thither.
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 Beth-peor: but no man knoweth of his sepulchre unto this day.
7 And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated.
Who was with Moses at the top of the mountain?
It was not the will of God that anyone should go up with Moses to the top of Pisgah. There he stood, upon a high prominence upon Pisgah’s top, in the presence of God and heavenly angels.
After he had viewed Canaan to his satisfaction, he lay down, like a tired warrior, to rest. Sleep came upon him, but it was the sleep of death. Angels took his body and buried it in the valley. The Israelites could never find the place where he was buried. His secret burial was to prevent the people from sinning against the Lord by committing idolatry over his body.
In Jude 1:9 we find the devil contending about the body of Moses but the Angel rebuked the devil.
Satan exulted that he had succeeded in causing Moses to sin against God. For this transgression, Moses came under the dominion of death. If he had continued faithful, and his life had not been marred with that one transgression, in failing to give to God the glory of bringing water from the rock, he would have entered the promised land, and he would have been translated to Heaven without seeing death.
Michael, with the angels that buried Moses, came down from Heaven, after he had remained in the grave a short time, and resurrected him, and took him to Heaven.
So it is good to understand that the Lord, via the Archangel Michael, buried the body of Moses but not before having a confrontation with the devil.
