2 Esdras 5:12-22

12 At that time people will hope for much, but will get nothing; they will work hard, but will never succeed at anything.
13 These are the signs of the end that I am permitted to show you. But if you begin to pray again and continue to weep and fast for seven more days, you will hear even greater things."
14 Then I woke up, and I was trembling violently. I was so disturbed that I was about to faint,
15 but the angel that had come to talk with me took hold of me, strengthened me, and set me on my feet.
16 The next night, Phaltiel, who was a leader of the people, came to me and asked, "Where have you been? And why do you look so sad?
17 Don't you know that the people of Israel in the land of their exile have been put in your care?
18 So get up and eat. Do not abandon us like a shepherd leaving his flock to the attacks of savage wolves."
19 "Leave me alone," I answered, "do not come near me for the next seven days. Then come back." So he left.
20 Then, crying and mourning, I fasted seven days, as the angel Uriel had commanded me to do.
21 At the end of the seven days, I was again deeply troubled,
22 but I recovered my ability to think, and again I began to speak with God Most High.
