2 Esdras 4:1-7

1 Then the angel that had been sent to me, whose name was Uriel, answered
2 and said to me, "Your understanding has utterly failed regarding this world, and do you think you can comprehend the way of the Most High?"
3 Then I said, "Yes, my lord." And he replied to me, "I have been sent to show you three ways, and to put before you three problems.
4 If you can solve one of them for me, I also will show you the way you desire to see, and will teach you why the heart is evil."
5 I said, "Speak on, my lord." And he said to me, "Go, weigh for me the weight of fire, or measure for me a measure of wind, or call back for me the day that is past."
6 I answered and said, "Who of those that have been born can do this, that you ask me concerning these 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 hell, or which are the entrances of paradise?'
