Isaiah 6:2-5

BSB(i) 2 Above Him stood seraphim, each having six wings: With two wings they covered their faces, with two they covered their feet, and with two they were flying. 3 And they were calling out to one another: “Holy, holy, holy is the LORD of Hosts; all the earth is full of His glory.” 4 At the sound of their voices the doorposts and thresholds shook, and the temple was filled with smoke. 5 Then I said: “Woe is me, for I am ruined, because I am a man of unclean lips dwelling among a people of unclean lips; for my eyes have seen the King, the LORD of Hosts.”
