Mark 3:31-35

And there come his mother and his brethren; and, standing without, they sent unto him, calling him. And a multitude was sitting about him; and they say unto him, Behold, thy mother and thy brethren without seek for thee. And he answereth them, and saith, Who is my mother and my brethren? And looking round on them that sat round about him, he saith, Behold, my mother and my brethren! For whosoever shall do the will of God, the same is my brother, and sister, and mother.
