Isaiah 6:2-4

2Above it stood the seraphims: each one had six wings; with two he covered his face, and with two he covered his feet, and with two he flew. 3And one cried to another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.12 4And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.3
