Acts 21:8, 9 - "The next day we left and came to Caes·a·re′a, and we entered the house of Philip the evangelizer, who was one of the seven men, and we stayed with him. This man had four unmarried daughters who prophesied."
Romans 16:1, 2 - "I am introducing to you Phoe′be, our sister, who is a minister [Gk. diakonos*] of the congregation that is in Cen′chre·ae, so that you may welcome her in the Lord in a way worthy of the holy ones and give her whatever help she may need, for she herself also proved to be a defender of many, including me."
* The same word is used of 'deacons' at Philemon 1:1; 1 Tim. 3:8, 12
Romans 16:7 - "Greet An·dron′i·cus and Ju′ni·as [Gk. Junia - a woman's name], my relatives and fellow prisoners, who are men well-known to the apostles [lit. 'notable (ones) in the apostles'- see KIT] and who have been in union with Christ longer than I have."
This Scripture is more ambiguous regarding Junia's status, but it's interesting that the RNWT still interprets the name as belonging to a male.
