2 Esdras 14:36-40 Common English Bible (CEB)

36. But let no one approach me now or come looking for me for forty days."

37. I took the five men, as he had commanded me, and we went out into the field and remained there.

38. So it happened to me on the next day that a voice called me: "Ezra, open your mouth and drink what I give you to drink."

39. So I opened my mouth, and a full cup was set before me. It was full of something like water, but its color was like fire.

40. I took it and drank, and when I had drunk it my heart poured forth understanding, and wisdom increased in my heart, for my spirit retained memory.
