2 Esdras 4:6-8

New Revised Standard Version, Anglicised

⁶ I answered and said, ‘Who of those that have been born can do that, that you should ask me about such things?’

⁷ And he said to me, ‘If I had asked you, “How many dwellings are in the heart of the sea, or how many streams are at the source of the deep, or how many streams are above the firmament, or which are the exits of Hades, or which are the entrances^[a] of paradise?” ⁸ perhaps you would have said to me, “I never went down into the deep, nor as yet into Hades, neither did I ever ascend into heaven.”
