Isaiah 6:1-7 (ESV)
1 In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. 2 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. 3 And one called to another and said:
“Holy, holy, holy is the Lord of hosts;
the whole earth is full of his glory!”
4 And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. 5 And I said: “Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the Lord of hosts!”
6 Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. 7 And he touched my mouth and said: “Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.”

Isaiah 52:13-15 (ESV)
13 Behold, my servant shall act wisely;
he shall be high and lifted up,
and shall be exalted.
14 As many were astonished at you—
his appearance was so marred, beyond human semblance,
and his form beyond that of the children of mankind—
15 so shall he sprinkle many nations.
Kings shall shut their mouths because of him,
for that which has not been told them they see,
and that which they have not heard they understand.

Isaiah 57:15 (ESV)
15 For thus says the One who is high and lifted up,
who inhabits eternity, whose name is Holy:
“I dwell in the high and holy place,
and also with him who is of a contrite and lowly spirit,
to revive the spirit of the lowly,
and to revive the heart of the contrite.
