metmom: Which is who exactly?"
Revelations 1:8 clearly refers to Isaiah 44:6, which speaks of Yahweh and Elohim.
If you wish to believe that Isaiah's words "Yahweh" and "Elohim" mean "Jesus", I will forbear and respectfully disagree.
Dude! I think you need to read Isaiah 44:6 again.
Isaiah 44:6 Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
Who is the King of Israel from the lineage of David?
