Verses 10:55-56 of 4 Ezra hint that the visual/audio revelations of the heavenly realm that Ezra experiences are so spectacular that humans cannot possibly comprehend them. This appears to be a running theme that the author of 4 Ezra employs over and again.(404, 407)
4 Ezra makes use of similar metaphors like those found in 1 Enoch. When comparing Ezra’s to Ezekiel’s revelation for instance there is a particular contrast between the two. Ezekiel is informed that he is to set his mind upon all that he is to see and hear and write it down for record, while Ezra is informed that he is to take in as much as his eyes and ears can handle. The difference is that Ezekiel’s revelation presents heaven in a manner which can be thoroughly received and interpreted by the human senses whereas Ezra’s revelation presents heaven as beyond the capacity of the human senses to completely receive and interpret.(405)
The use of language with emphasis on the word ‘foundation’ (as it applies to the city in 4 Ezra) is also worthy of note. ‘Foundations’ are usually mentioned with reference to either the total destruction or complete rebuilding of a city or temple.(402) The city and the earth serve to lay the groundwork for what may be unpacked by later apocalyptic, or prophetic literature. There are numerous instances where the term ‘foundation’ is found outside of 4 Ezra. Just consider 2 Samuel, Psalms, Job, Proverbs, and Isaiah as examples.
