Herald
A herald is the voice through which a higher authority publishes a binding word — a king's decree, a coming epiphany, an indictment of an age, or the gospel itself. UPDV preserves the literal noun once, in a Babylonian throne-room scene, and elsewhere uses "preacher" for the same office: someone whose mouth carries another's message into public hearing.
The Royal Crier
The plainest picture is administrative. When Nebuchadnezzar erects the gold image on the plain of Dura, the proclamation does not come from the king's own lips but through an officer whose job is to publish it: "Then the herald cried aloud, To you⁺ it is commanded, O peoples, nations, and languages," (Dan 3:4). The herald has no message of his own. He has volume, scope, and a script — the word he cries belongs to the throne behind him, and the address is plural and total ("you⁺ … peoples, nations, and languages").
The Voice in the Wilderness
The prophetic herald carries the same shape — a voice publishing another's coming — but the throne is Yahweh's and the venue is open country, not a court. Isaiah hears it as a single cry breaking out ahead of God's arrival: "The voice of one who cries, Prepare⁺ in the wilderness the way of Yahweh; make level in the desert a highway for our God" (Isa 40:3). The plural-you imperative ("Prepare⁺ … make level") makes the audience the people, not just the prophet; the herald's cry conscripts the hearers into roadwork for the divine procession.
The Preacher of Righteousness
The herald-image reaches back before Israel. Peter places Noah in the role for the antediluvian world: God "did not spare the ancient world, but preserved Noah with seven others, a preacher of righteousness, when he brought a flood on the world of the ungodly" (2Pe 2:5). The vocabulary that appears here — "preacher" — is the same word UPDV uses of Paul's apostolic commission, and is flagged in the topical tradition as the New Testament's herald-equivalent. Noah's preaching is set against an "ungodly" hearership and is paired with the flood that follows; the herald's word, refused, becomes the prosecution's exhibit.
The Apostolic Commission
Paul takes up the herald-vocabulary for himself, twice, in nearly identical phrasing. To Timothy he writes that to the gospel "I was appointed a preacher and an apostle (I speak the truth, I don't lie), a teacher of the Gentiles in faith and truth" (1Ti 2:7), and again, "to which I was appointed a preacher, and an apostle, and a teacher" (2Ti 1:11). Three offices stack: the herald who publishes, the apostle who is sent, the teacher who explains. The parenthetical oath in 1Ti 2:7 ("I speak the truth, I don't lie") is the herald's credential — a public claim that the message he carries is not his own invention. The Gentile scope in the same verse extends the herald's reach in a direction the Daniel scene only previews: "peoples, nations, and languages" become the addressee not by royal accident but by appointment.
The Shape of the Office
Across these five UPDV witnesses the herald's office holds a stable shape. He is appointed, not self-commissioned (1Ti 2:7, 2Ti 1:11). His audience is plural and public — a crowd, a wilderness, an "ancient world" (Dan 3:4, Isa 40:3, 2Pe 2:5). His message is not his own; it belongs to a throne, a coming God, or "righteousness" (Dan 3:4, Isa 40:3, 2Pe 2:5). And the response of the hearers is itself part of the proclamation's outcome — refusal in Noah's day brings the flood, and Isaiah's cry presupposes that the road can in fact be made ready.
