As I looked, I saw a great storm coming from the north, driving before it a huge cloud that flashed with lightning and shone with brilliant light. There was fire inside the cloud, and in the middle of the fire glowed something like gleaming amber. From the center of the cloud came four living beings that looked human, except that each had four faces and four wings. Their legs were straight, and their feet had hooves like those of a calf and shone like burnished bronze. Under each of their four wings I could see human hands. So each of the four beings had four faces and four wings. The wings of each living being touched the wings of the beings beside it. Each one moved straight forward in any direction without turning around.
