Isaiah 6:2-4

Darby Translation

² Seraphim were standing above him: each had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he flew.

³ And one called to the other and said, Holy, holy, holy is Jehovah of hosts; the whole earth is full of his glory!

⁴ And the foundations of the thresholds shook at the voice of him that cried, and the house was filled with smoke.
