Isaiah says he saw the Lord sitting on a throne, high and lifted up, with the train of his robe filling the temple (Isaiah 6:1). Seraphim call “Holy, holy, holy,” and the foundations shake while the house fills with smoke (Isaiah 6:2-4).
Isaiah dates his experience to the year King Uzziah died and reports seeing the Lord enthroned in the temple, towering in majesty as the robe’s trailing hem fills the space. Heavenly attendants (seraphim) stand above, using their six wings for covering and for flight. Within Isaiah, this scene functions as a throne-room vision that introduces the prophet’s commissioning narrative (continuing in Isaiah 6:5–8).
Isaiah locates this scene in a moment of national transition: “the year King Uzziah died.” In that setting he reports a throne-room vision centered in the temple. The Lord is presented as the true king—“high and lifted up”—and the imagery of the robe’s trailing hem filling the temple communicates overwhelming majesty and presence (textual claim).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Isaiah 6:1, then read the surrounding section so the answer stays connected to the passage's flow.
1In the year that king Uzziah died I saw the Lord sitting on a throne, high and lifted up; and his train filled the temple.
