>>Revelations 1:8 clearly refers to Isaiah 44:6, which speaks of Yahweh and Elohim.<<

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?

CynicalBear: "Who is the King of Israel from the lineage of David?"

The correct translation in Isaiah 44:6 for those various names of God is:

Yahweh is Israel’s Melek and Go’el.
He is Yahweh Tsebaoth.

This is what Yahweh says:
I am the first and the last,
and there is no Elohim except me.

All of these are names of God, not a Davidic king of Israel.
