Matthew 12:49

47Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee.

48But he answered and said unto him that told him, Who is my mother? and who are my brethren?

49And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren!

50For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
