Jesus knew why His family had come for Him.
At the wedding in Cana He had to stop her with
"Woman what have I to do with thee?" when
she tried to help Him.

Now they were trying to interfer so He had to
stop them by stretching out His hands towards
His disciples and said, "Behold my mother and
my brethren! For whosoever shall do the will
of God, the same is my brother, and my sister,
and mother" Mark 3:34,35
