Revelation 4:7

The description of these living creatures does not exactly agree with any of the O. T. parallels: in Ezekiel 1, which is the nearest, the four Cherubim, as they are called, have human figures, calves" feet, and eachhas four faces, of the same four animals as these: also they have each four wings, while these have six, like the Seraphim of Isaiah 6:2. Probably the meaning is, that these four represent the Cherubim andSeraphim who "continually do cry -Holy, Holy, Holy, Lord God of Sabaoth"." We have no reason to suppose that the Angels, or these super-angelic Beings, have proper bodies or invariable forms: they appear in such forms as may please God, or may be appropriate to the purpose for which He bids them appear. For further discussion as to their meaning, see Excursus I.
