In the Olivet Discourse where Jesus responds to the question about the sign of his coming and the end of the age, Jesus focused upon seeing the abomination of desolation mentioned in the prophecies of Daniel. Scholars have long debated what he meant. In Daniel chapter 8, a prophecy is described that refers to 2,300 days, and its meaning would only be understood at the “time of the end.” [Dan. 8:17] When Jesus referred to one of the prophecies of Daniel in connection with the “sign” of the end time, he must have meant that when Daniel’s prophecies are understood, that would be the sign of his coming that the disciples requested.
In his commentary on Ezekiel, George Currey (1816-1885) discussed the relationship between Ezekiel and the Apocalypse of John, and he pointed out some striking differences.
One of the ways the accounts differ is in their respective descriptions of God’s throne. Currey notes some differences between the accounts in the following paragraph. 
In Musings on the ‘Flat Earth and Firmament’, John Wright says, “The more one reads the bible, the more one should notice the primitive cosmological understanding of its authors.” Wright depicts his views on ancient Hebrew cosmology in a colorful graphic, claiming that their conception, which they shared with other peoples of the ancient world, was that the heaven was a solid dome, that supported water above. He quoted the opinion of P. H. Seely, and Jewish writings from the hellenistic era, to support his view. Wright stated:
And so the Hebrews shared the same cosmological ideas as the rest of the Ancient Near East, including Egypt, Babylonia, Canaan, etc. whose writings also reflect the fact.
The firmament as a solid object is confirmed in Job: ‘Can you join him in spreading out the skies, hard as a mirror of cast bronze?’ (Job 37:18), and in Ezekial: ‘Spread out above the heads of the living creatures was what looked something like a firmament, sparkling like crystal, and awesome.’ (Ezekial 1:22). It was regarded as a beautiful feat of engineering (as in fact it is, in a way), and they told God they appreciated it: ‘The heavens are thy handiwork.’ (Psalms 102).
In support for his conclusions Wright cited the book of Enoch, and the Apocalypse of Baruch, where in 3 Apoc. Bar. 3.7, the author speculates on whether the rigid heaven consists of clay, copper or iron.
