Jacob wrestling with G-d?  That was also the Messiah.

Moses wrote the Torah at G-d's direction.  Messiah says Moses wrote about Him (John 5:46).

G-d speaking to Moses at the burning bush (Exodus 3:13-15)?

That was Yeshua, too.  Messiah identifies Himself as the "I AM" (John 8:53-58).

Mount Sinai and the giving of the Torah?  In Exodus 24:9-11 Moses, Aaron, Nadab, Abihu, and the seventy elders of Israel went up and saw the G-d of Israel

Twice!

Once in verse 10 and once in verse 11, yet Messiah states nobody has seen the Father (John 6:46).  So who was it Moses and the other men saw?

They saw Messiah Yeshua!  He is the same yesterday, today, and forever (Hebrews 13:8).
