How about the distinction between a title and a description?

In the Hebrew text there is no distinction made. He calls the man (male) and the "son of man" (human) on His right hand (not seated at His right side). There is no title there.

As to the "son of man" in Hebrew, the writer of Psalms 80:17-18 introduces one as seated on the right hand of God but the concept is brought into focus in the apocalyptic writings of Daniel 7 and the Similitudes of Eth. Enoch (chpts. 31-71). Jesus is just applying the apocalyptic messaniac title to Himself.

“God is not a man, that he should lie, nor a son of man, that he should change his mind” [Num 23:19]"

"In the Hebrew text there is no distinction made. He calls the man (male) and the "son of man" (human) on His right hand (not seated at His right side). There is no title there."

There is a distinction by context. Numbers by parallelism "is not a man" and "nor a son of man" and Psalms by title "upon the son of man". Whether seated or standing, "on the right hand" designates a position of power and prestige.
