Isaiah 6
2 Ref Above him stood the seraphim. Each one had six wings. With two he covered his face. With two he covered his feet. With two he flew.
3 Ref One called to another, and said, "Holy, holy, holy, is Yahweh of Hosts! The whole earth is full of his glory!"
4 Ref The foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke.
