"13. The last proposition of Helvidius was this, and it is what he wished to show when he treated of the first-born, that brethren of the Lord are mentioned in the Gospels. For example, Matthew 12:46 Behold, his mother and his brethren stood without, seeking to speak to him. And elsewhere, John 2:12 After this he went down to Capernaum, he, and his mother, and his brethren. And again, John 7:3-4 His brethren therefore said unto him, Depart hence, and go into Judæa, that your disciples also may behold the works which you do. For no man does anything in secret, and himself seeks to be known openly. If you do these things, manifest yourself to the world. And John adds, John 7:5 For even his brethren did not believe in him. Mark also and Matthew, And coming into his own country he taught them in their synagogues, insomuch that they were astonished, and said, Whence has this man this wisdom, and mighty works? Is not this the carpenter's son? Is not his mother called Mary? And his brethren James, and Joseph, and Simon, and Judas? And his sisters, are they not all with us? Luke also in the Acts of the Apostles relates, Acts 1:14 These all with one accord continued steadfastly in prayer, with the women and Mary the mother of Jesus, and with his brethren."

And in the eighth day the flesh of his foreskin shall be circumcised. And she shall continue in the blood of her purifying three and thirty days. She shall touch no hallowed thing, and so forth."
