Is there an oral tradition or oral history within the Jewish faith that makes mention of a conflict between Michael the Archangel and satan over the body of Moses?
Interesting question. Here is what I found:
Legend makes Michael the teacher of Moses; so that the Israelites are indebted to their advocate for the supreme good of the Torah. This idea is alluded to in Midrash Deuteronomy Rabbah xi. 6 in the statement that Michael declined to bring Moses’ soul to God on the ground that he had been Moses’ teacher.
Michale is said to have had a discussion with Samael over the soul of Moses (Midrash Deut. Rabbah xi. 6.) According to the Zohar, Michael accompanies the souls of the pious and helps them to enter the gates of the heavenly Jerusalem. It is said that Michael and his host are stationed at the gates of the heavenly Jerusalem and give admittance to the souls of the just. Michael’s function is to open the gates also of justice to the just. It is also said that at the resurrection Michael will sound the trumpet, at which the graves will open and the dead will rise
The allusion in Jude v. 9 to the contention of the archangel Michael for the body of Moses belongs to a group of traditions which have been collected by R. H. Charles (Assumption of Moses, pp. 105 seq.), and it appears that the incident was familiar to Clement of Alexandria, Origen and other early writers
This last paragraph does not seem to be relating to Jewish oral tradition. I never heard of Jude v.9. Is that a Christian text?
Yep the letter of Jude is in the New Testament…
It is a short text only 25 verses.
Here is a link to the text: usccb.org/nab/bible/jude/jude.htm
1:9 But even when Michael the archangel was arguing with the devil and debating with him concerning Moses’ body, he did not dare to bring a slanderous judgment, but said, “May the Lord rebuke you!”
