'I Am the First' in the Bible

I am the first that saith unto Zion, Behold, behold them; and I will give to Jerusalem one that bringeth good tidings.

Thus saith Jehovah, the King of Israel, and his Redeemer, Jehovah of hosts: I am the first, and I am the last; and besides me there is no God.

Hearken unto me, O Jacob, and Israel my called: I am he; I am the first, I also am the last.
