Ezekiel 1:6-9

Each had four faces, and each had four wings. Their legs were straight, but they had hooves like calves. Their hooves were bright and glistening like polished brass. All four of them had faces and wings, and each of the supernatural beings had a pair of human hands under its wings. There were hands on all four sides of the living creatures. They joined one another with their wings, forming a square. When they moved forward in whatever direction, they went together as a group, without turning their bodies.
