No man knoweth of his sepulchre - Hardly, lest the grave of Moses should become an object of superstitious honor, because the Jews were not prone to this particular fore of error. Bearing in mind the appearance of Moses at the Transfiguration Matthew 17:1-10, and what is said by Jude Jude 1:9, we may conjecture that Moses after death passed into the same state with Enoch and Elijah; and that his grave could not be found because he was shortly translated (transported) from it.
