“brethren” = “brothers.”
I am online. I would have to go upstairs to get my KJV.
NIV is good enough for this discussion.
brethren = brothers.Not in the biological sense. You are trying to prove a falsehood. Your apparent reliance on bigots for education is showing. There is ZERO historical support for the heretical, anti-Catholic bigotry behind the claims of Mary having had many children.
