and he went and lived in a town called Nazareth. So was fulfilled what was said through the prophets, that he would be called a Nazarene.
Genesis 49:26 :
The blessings of your father are mighty beyond the blessings of my parents, up to the bounties of the everlasting hills. May they be on the head of Joseph, and on the brow of him who was set apart (נָזִר nazir) from his brothers.
So the simple fact that Jesus is 'from Nazaret' implies not only that Jesus has to be called 'Nazarene', but also that the he has to have Brothers there and he has to be 'set apart from his brothers'. So it is implicit in nuce the negation of a carnal brotherhood just when it is claimed.
Now, it would be not a coincidence that the Brothers of the Patriarch Joseph bear quasi the same names of the Brothers of Jesus listed by who knew them precisely…. ...in Nazaret !
Mark 6:3
3 Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him.
Genesis 49:16 gives not only Brothers to Jesus as Nazarene, but also an earthly father named Joseph, as the patriarch who receives the blessing in Gen 49:16.
