Matthew 12:49

47One said to him, “Behold, your mother and your brothers stand outside, seeking to speak to you.”

48But he answered him who spoke to him, “Who is my mother? Who are my brothers?”

49He stretched out his hand toward his disciples, and said, “Behold, my mother and my brothers!

50For whoever does the will of my Father who is in heaven, he is my brother, and sister, and mother.”
