Isaiah 6:1-8; Exodus 3:4-6; Revelation 4:8-11

1 In the year that King Uzziah died, I saw the Lord sitting on a throne, high and lofty; and the hem of his robe filled the temple. 2 Seraphs were in attendance above him; each had six wings: with two they covered their faces, and with two they covered their feet, and with two they 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 The pivots on the thresholds shook at the voices of those who called, and the house filled with smoke. 5 And I said: "Woe is me! I am lost, for I am a man of unclean lips, and I live among a people of unclean lips; yet my eyes have seen the King, the Lord of hosts!" 6 Then one of the seraphs flew to me, holding a live coal that had been taken from the altar with a pair of tongs. 7 The seraph touched my mouth with it and said: "Now that this has touched your lips, your guilt has departed and your sin is blotted out." 8 Then I heard the voice of the Lord saying, "Whom shall I send, and who will go for us?" And I said, "Here am I; send me!"
4 When the Lord saw that he had turned aside to see, God called to him out of the bush, "Moses, Moses!" And he said, "Here I am." 5 Then he said, "Come no closer! Remove the sandals from your feet, for the place on which you are standing is holy ground." 6 He said further, "I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob." And Moses hid his face, for he was afraid to look at God.
8 And the four living creatures, each of them with six wings, are full of eyes all around and inside. Day and night without ceasing they sing, "Holy, holy, holy, the Lord God the Almighty, who was and is and is to come." 9 And whenever the living creatures give glory and honor and thanks to the one who is seated on the throne, who lives forever and ever, 10 the twenty-four elders fall before the one who is seated on the throne and worship the one who lives forever and ever; they cast their crowns before the throne, singing, 11 "You are worthy, our Lord and God, to receive glory and honor and power, for you created all things, and by your will they existed and were created."
