His brethren - There has been some difference of opinion about the persons who are referred to here, some supposing that they were children of Mary his mother, others that they were the children of Mary, the wife of Cleophas or Alpheus, his “cousins,” and called “brethren” according to the customs of the Jews. The natural and obvious meaning is, however, that they were the children of Mary his mother. See also Mar_6:3. To this opinion, moreover, there can be no valid objection.
ومع ذلك المعنى الطبيعي والواضح انهم ابناء ماري واخوته وهذا الرآي علاوة على ذلك من الممكن الا يوجد له اعتراض صحيح .......

الخلاصة ان عذرية العذراء أمر مشكوك فيه
