Ezekiel 1:6-9

but each had four faces, and each of them had four wings. Their legs were straight, and the soles of their feet were like the sole of a calf’s foot. And they sparkled like burnished bronze. Under their wings on their four sides they had human hands. And the four had their faces and their wings thus: their wings touched one another. Each one of them went straight forward, without turning as they went.
