In Zech 14:9, we read:
And Yahweh shall be
king over all the earth: in that day shall there be one Yahweh, and his name
one (אֶחָד). (KJV,
slightly revised)
This text, speaking of a then-future event, is of importance to the LDS
vs. (Creedal) Trinity debate. How so? In this text, a single person, evidenced
by “king” being singular (מֶלֶךְ), not three
persons, is called Yahweh and is also said, mirroring Deut 6:4, to be “one” (אֶחָד). The LXX substantiates this, using the
singular for "king" (βασιλέα) and the neuter εν for “one,” corresponding to the
neuter ονομα (“name”
[singular]). So, in this passage, not only is there a distinction between
the persons, but between YHWH and the other persons (regardless of whether one believes the text is speaking of the Father or Son)—the former tolerated with a
lot of qualifications and ambiguities in Trinitarianism; the latter is not.
This is further problematic as Zech 14:9, speaking of a single divine person,
is mirroring Deut 6:4, a common “proof-text” Trinitarians (abuse) to support
their theology.

On the singular name, one might be tempted to draw a parallel to Matt
28:19, a common Trinitarian “proof-text.” For a discussion, see:
