The Book of Moses uses the phrase “son of man” multiple times such as in 7:3:
And it came to pass that when Moses had said these words, behold, Satan came tempting him, saying: Moses, son of man, worship me. (emphasis added)
Jeffrey M. Bradshaw explains the significance of this phrase:
1 Enoch’s Book of Parables holds special interest for students of the book of Moses. Both books describe visions of Enoch with a central figure and a common set of titles. The title “Son of Man,” which is a notable feature of the Book of Parables, also appears in marked density throughout Enoch’s grand vision in the book of Moses. The titles “Chosen One,” “Anointed One,” and “Righteous One” also appear prominently in both texts. Consistent with the conclusions of Nickelsburg and VanderKam about the use of these multiple titles in the Book of Parables, the book of Moses applies them all to a single individual. Moreover, Moses 6:57 gives a single, specific description of the role of the Son of Man as a “righteous judge.” According to Nickelsburg and VanderKam, this conception is highly characteristic of the Book of Parables, where the primary role of the Son of Man is also that of a judge.– Jeffrey M.
