Isaiah 6:1-3

In the year that King Uzziah  died, I saw the Lord  seated on a high and lofty  throne,  and the hem of his robe filled the temple. Seraphim  were standing above him; they each had six wings:  with two they covered their faces, with two they covered their feet, and with two they flew.  And one called to another: Holy, holy, holy is the  LORD of Armies; his glory  fills the whole earth.
