2 Esdras 14:40 In-Context

38 And the next day, behold, a voice called me, saying, Esdras, open thy mouth, and drink that I give thee to drink.
39 Then opened I my mouth, and, behold, he reached me a full cup, which was full as it were with water, but the colour of it was like fire.
40 And I took it, and drank: and when I had drunk of it, my heart uttered understanding, and wisdom grew in my breast, for my spirit strengthened my memory:
41 And my mouth was opened, and shut no more.
42 The Highest gave understanding unto the five men, and they wrote the wonderful visions of the night that were told, which they knew not: and they sat forty days, and they wrote in the day, and at night they ate bread.
