The last part of the passage (John 3:5) literally reads: “except anyone is born of water and [kai] Spirit, he cannot enter into the kingdom of the God.” As seen, in allowable contexts the Greek conjunction kai (“and”) could be translated as an ascensive conjunction “even,” which could explain the previous clause: “born of water.” Thus, it could be translated: “except anyone is born of water even [kai] Spirit, he cannot enter into the kingdom. . . .”
Second, I'd like to know if John 3:5 is one of these "allowable contexts"?
Could "kai" be translated as an "ascensive conjunction" ("even") here?
