Well since Psa.45 is about the marriage of the Messiah to His people, you've made our King an adulterer, because He's marrying His Fathers' people...Who is also the King of His people. You have Two Husbands and Two Kings.
Heb.1 shows how angels worshipped the Messiah when He was born on earth and Hebrews goes on to show that unlike Adam, Jesus possessed eternal life before He rose from death.
I'm dealing with all the scripture you've cited so far and comparing it in a sensible manner.
On the name "Jehovah", their rabbis' thought it meant "I will be what I will be."
They weren't sure what YHVH meant, but when God provlaimed His Name He said,
I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy...Thou canst not see my face: for there shall no man see me, and live...it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by: And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen.
Exo.33:19-20,22-23 KJV
So the rabbis' thought "I will be"... gracious, merciful....what else? They believed YHVH contained all the attributes of God. That describes Jesus.
I think He showed Moses the beating His back got.
