WHO BURIED MOSES?

He buried him = Jehovah (Yehovah) buried Moses. Said of no other. Hence, when raised for the Transfiguration, Satan, who has the power of death (Heb. 2:14), "contended" with Michael about his body, Jude 9. So God has buried the Law for those who, being "in Christ". have died and are dead to the Law. Cp. (Rom. 6.2, 6-8).

Deuteronomy
34:5    So Moses the servant of the LORD died there in the land of Moab, according to the word of the LORD.
34:6   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.
34:7   And Moses was an hundred and twenty years old when he died: his eye was not dim, nor his natural force abated.

From reading the above three verses of Deuteronomy, Moses was with the LORD, Yehovah buried Moses' body.

Hebrews
2:14    Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;

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.

Romans
6:2    God forbid. How shall we, that are dead to sin, live any longer therein?
6:6    Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
6:7    For he that is dead is freed from sin.
6:8    Now if we be dead with Christ, we believe that we shall also live with him:

Now that we have covered Biblical descriptions of the death of Moses, here is a paragraph from the writings of Josephus, a Hebrew historian.

The Antiquities of the Jews 4.8.325 (Josephus/The Complete Works)
This is not in the Bible, it is in the historic records of Josephus.

Now as soon as they were come to the mountain called Abarim (which is a very high mountain, situated over against Jericho and one that affords, to such as are upon it, a prospect of the greatest part of the excellent land of Canaan), he dismissed the senate; 326and as he was going to embrace Eleazar and Joshua, and was still discoursing with them, a cloud stood over him on the sudden, and he disappeared in a certain valley, although he wrote in the holy books that he died, which was done out of fear, lest they should venture to say that, because of his extraordinary virtue, he went to God.
