2 Esdras 14:38-40

Common English Bible

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.
