Second, I'd like to know if John 3:5 is one of these "allowable contexts"?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.”[8] 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. . . .”
Could "kai" be translated as an "ascensive conjunction" ("even") here?
