NWT;verse 17`GREET Andronicus and Junias....who are men of note.'
I understand from NIV STUDY BIBLE that Junias is feminine.
ia is feminine ending.eg filia for daughter
us for masculine;eg Julius
Verse 13;NWT; Greet Rufus...his mother and mine.
NIV;his mother who has been a mother to me
verse 23;NWT;Erastus...Quartus his brother
NIV;our brother Quartus;metaphorically speaking.
I humbly suggest WT should relook at the above verses and retranslate.
I f anyone can prove the NWT version is superior,I will join Jws
