“While he yet talked to the people, behold, his mother and his brethren stood without, desiring to speak with him.”
King James Version (KJV)
12:46 His brethren - His kinsmen: they were the sons of Mary, the wife of Cleopas, or Alpheus, his mother's sister; and came now seeking to take him, as one beside himself, #Mark 3:21|. #Mark 3:31|; Luke 8:19.
Mt 12:46,47 [His] mother and his brethren. On the brethren of the Lord, see PNT "Mt 13:55". His brethren did not yet believe in him. Compare Mr 3:31-35 Lu 8:19,21.
