Isaiah 6:2-4 Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.

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