The commentary of Origenes in book 10 finishes with John 2:25 and book 13 starts with John 4:13.
Chapter 3 contains many important points that are misunderstood in Christianity today, and we are poorer for not having the wisdom of Origenes available to us. The chapter contains a very important discussion about reincarnation between Nicodemus and Jesus. How did Origenes view the concept of “being born again”? It also contains the most often quoted verse of the bible John 3:16. It is a shame that 3:17 is not included in the latter’s popularity.
