Contradiction with Isaiah 6:2
Isaiah describes seraphim having six wings, which contrasts with the four living creatures in Ezekiel 1:7 that have straight feet and are described differently.
Isaiah 6:2: Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
Contradiction with Revelation 4:8
In Revelation, each of the four beasts has six wings, contradicting the depiction in Ezekiel where the creatures are described with feet like a calf's foot and burnished brass.
Revelation 4:8: And the four beasts had each of them six wings about [him]; and [they were] full of eyes within: and they rest not day and night, saying, Holy, holy, holy, Lord God Almighty, which was, and is, and is to come. [rest...: Gr. have no rest]
Contradiction with Daniel 10:6
Daniel's vision describes a figure with arms and feet like polished brass, which is different from Ezekiel 1:7 where only the feet are mentioned in this manner.
Daniel 10:6: His body also [was] like the beryl, and his face as the appearance of lightning, and his eyes as lamps of fire, and his arms and his feet like in colour to polished brass, and the voice of his words like the voice of a multitude.
