Isaiah six, verses one through three, opens the prophet's own account of his commissioning with a vision set in the year King Uzziah died. Isaiah reports seeing the Lord seated on a high and lofty throne, the train of his robe filling the temple, attended by seraphim, six winged beings who cover their faces with two wings, their feet with two more, and fly with the remaining two. The seraphim call to one another in words that became one of scripture's most repeated liturgical formulas, holy, holy, holy is the Lord of hosts, the whole earth is full of his glory, a threefold repetition read since antiquity as an intensifying superlative rather than as three separate claims. The vision is set specifically within the temple, giving Isaiah's commissioning a concrete architectural and cultic setting rather than a placeless or purely inward experience, and the passage's opening date, tied to a named king's death, anchors the vision to a specific moment in Judah's political history rather than leaving it undated, a detail scholars have used to place the call narrative within the prophet's own lifetime rather than treating it as a timeless or purely symbolic scene detached from any historical setting.
