Contradiction with John 1:18

Contradiction with 1 Kings 22:19
Describes God on His throne with all hosts of heaven, without mention of covering as in Isaiah 6:2 with the seraphim.

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]
