Mark 3:31-35 King James Version (KJV)
31 There came then his brethren and his mother, and, standing without, sent unto him, calling him.
32 And the multitude sat about him, and they said unto him, Behold, thy mother and thy brethren without seek for thee.
33 And he answered them, saying, Who is my mother, or my brethren?
34 And he looked round about on them which sat about him, and said, Behold my mother and my brethren!
35 For whosoever shall do the will of God, the same is my brother, and my sister, and mother.
