Kommentar zu Jechezkiel 1:6

and each one had four faces “Each one” means that the human countenance had four faces, as did that of the lion, the eagle, and the ox, totaling sixteen [faces] to one living being. It was thus for each living being, and four wings for each of the faces, totaling sixty-four wings for each living being. This is [why] Jonathan paraphrased: two hundred fifty-six wings.
