Hovering about Him were mighty, six-winged angels of fire. With two of their wings they covered their faces, with two others they covered their feet, and with two they flew. In a great antiphonal chorus they sang, “Holy, holy, holy is the Lord Almighty; the whole earth is filled with His glory.” Such singing it was! It shook the Temple to its foundations, and suddenly the entire sanctuary was filled with smoke.
