Isaiah 44:6
The context
Isaiah 44 continues the Cyrus material and turns to a sustained polemic against idol manufacture, which occupies most of the chapter. The verse opens with the divine title and the claim of exclusivity, addressing Israel as witness. The following verses parody the craftsman who makes a god from the same wood he burns.
What it establishes
The verse claims eternity and exclusivity for Yahweh in the strongest available terms, using the title of first and last. It also frames the claim as a word to Israel rather than a general philosophical thesis.
What it does not establish
It does not by itself establish Trinitarian distinctions. The sentence is a claim about exclusivity and priority; the application of the title to Christ in Revelation is a later identification. Nor does it address other heavenly beings, since the polemic concerns manufactured gods.
