Are you responding to me?
I am only saying that In my Kjv Jesus used the word Cephas in John1:42.
Cephas is Aramiac for rock, the greek makes it stone but it is the same thing, it comes out as peter in english from the greek, but is the same thing.
Jesus spoke in Aramaic Cephas means the same as our english rock but in any event changing the word would not change the meaning, what ever Jesus had in mind is the same regardless of the language it is translated to.
So what he said in his own language is all that matters.
