We read in Jn 19:19(KJV):
Pilate wrote a title, and put it on the cross. And the writing was Jesus Of Nazareth The King Of The Jews.
In some other versions like LSB, it reads as JESUS THE NAZARENE.
In the New Testament, Nazarene was a title applied to Jesus and, later, to those who followed his teachings (Acts 24:5). In the Greek text there appear two forms of the word: the simple form, Nazarēnos, meaning “of Nazareth,” and the peculiar form, Nazōraios. Before its association with the locality, this latter term may have referred to a Jewish sect of “observants,” or “devotees,” and was later transferred to the Christians(Courtesy: britannica.com)
A doubt arises as to why the locality of Nazareth by which Jesus was popularly known,was of significance to the Roman Governor. But in case Pilate had in mind the term Nazoraios, he intended to project Jesus as a devotee and observant of Jewish Law, and not as someone who took up arms and revolted like the Zealots. That possibility is evident where Pilate advocates for release of Jesus as the crowd shouts for the release of Barabbas who had been in prison for armed revolt ( Lk 23:22-25) My question therefore, is: What does 'N' in INRI actually stand for?
