Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew.
"Seraphim": described here as the 'messengers in the divine council', but has no real biblical parallel. The root word ś-r-p, for Seraph, gives a portrayal of the 'burning ones'.
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.
The verb rendered “I am undone” (nidmeti) is ambiguous. J. J. M. Roberts argues that Isaiah is deliberately exploiting a double meaning, since the word can signify both “I am destroyed” and “I am silenced,” and the passage’s repeated emphasis on lips, ending with the seraph touching Isaiah’s lips with a coal before his commission, supports hearing both senses at once.
Isaiah's commission from the Lord (6:8–13)
Verse 8
Also I heard the voice of the Lord, saying,
Whom shall I send,
and who will go for us?
Then said I,
Here am I; send me.
"Us": the plural form refers to 'the entire divine assembly'.
"Here am I; send me": This declaration is remarkable because it is in contrast to the despair Isaiah expresses in verse 5 and for the observation that his human voice is heard in the heavenly court (cf. 1 Kings 22:19–23; Revelation 5:1–14). The Jerusalem Bible notes Abraham and Isaiah as examples of biblical characters who readily respond, and contrasts them with Moses and Jeremiah, whose response is hesitant.
