2 Esdras 14:39-41

Revised Standard Version

³⁹ Then I opened my mouth, and behold, a full cup was offered to me; it was full of something like water, but its color was like fire. ⁴⁰ And I took it and drank; and when I had drunk it, my heart poured forth understanding, and wisdom increased in my breast, for my spirit retained its memory; ⁴¹ and my mouth was opened, and was no longer closed.
