Enat, it wasn't God, and it wasn't even Moses who said it. It was John, or whoever wrote this, who intentionally misquoted the Old Testament
There is nothing in it about the Son of Man (be adam which, btw, has no special meaning in Hebrew). John' didn't misquote; either he altered the OT verse to make it "fit" Christan theology, or a scribe who copied it did. Late 1st century attempts at "correction."
Regardless of the (im)morality of altering the Bible which is too common an occurrence in it, the fact remains that John's (or whosoever) verse doesn't prove anything about Exodus.
“Enat, it wasn’t God, and it wasn’t even Moses who said it. It was John”
Son of a gun, I thought it was Jesus who said it to Nicodemus, just before He said “For God so loved the world....” Imagine God letting John in all that He had planned after John was guilty of misquoting the “Lamb, slain from the foundation of the world”.
