Isaiah 6:3-5

3And one called out to another, saying, “Holy, Holy, Holy is the Lord of hosts; The whole earth is filled with His glory.”

4And the foundations of the thresholds trembled at the voice of him who called out, and the temple was filling with smoke.

5Then I said, “Woe is me! For I am ruined, Because I am a man of [ceremonially] unclean lips, And I live among a people of unclean lips; For my eyes have seen the King, the Lord of hosts.”
