Isaiah Sees the Holy King and Accepts a Commission

Uzziah's death year opens a throne that outlasts a king

In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple. Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly. And one cried unto another, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory. The posts of the door moved at the voice, and the house was filled with smoke.

The vision is temple-shaped: throne, attendants, smoke, altar. Seraphim and six wings are the scene's holy court, not a diagram to literalize into a racialized deity or a private visionary career. The year of a long reign's end makes the living King the point.

Uncleanness is confessed, a coal touches the mouth, and the prophet answers

Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, the LORD of hosts. A seraph lays a live coal from the altar upon his mouth: Lo, this hath touched thy lips; and thine iniquity is taken away, and thy sin purged. The voice of the Lord says, Whom shall I send, and who will go for us? Then said I, Here am I; send me.

Cleansing comes from the altar before the commission. The volunteer is a purged speaker, not a self-authorized leader. The vision does not license untested claims to have seen God, and it does not turn smoke and wings into a method.
