Ezekiel 1:6-9 NKJV
Each one had four faces, and each one had four wings. Their legs were straight, and the soles of their feet were like the soles of calves’ feet. They sparkled like the color of burnished bronze. The hands of a man were under their wings on their four sides; and each of the four had faces and wings. Their wings touched one another. The creatures did not turn when they went, but each one went straight forward.
