Mark 3:21
When His relatives [or friends] heard about this [i.e., all that He was doing], they went out to take custody of Him [for safety reasons?], for people were saying, "He has lost his mind."
Mark 3:31-35
Then Jesus' mother and [half-] brothers came and stood outside [i.e., of a large house. See Matt. 12:46-13:1]. They sent a message to Him, asking Him to come out to them.
2 Corinthians 5:16
So, from now on we will not regard any person by worldly standards, even though we [once] regarded Christ that way. But we will not regard Him [that way] anymore. [Note: Paul seems to be saying that before his conversion he viewed Christ on the basis of His family, His education, His position, etc., but since his conversion he does not view Him that way anymore].
