And the Seraphim stood round about Him, each one had six wings, and with two they were covering His face, and with two they were covering His feet, and with two they were flying; and they cried out one to the other, and said, Holy, holy, holy is the Lord of Sabaoth, the whole earth is full of His majesty.” Isa. vi. 1–3.
