'Brothers' in the Bible

After this he went down to Capernaum with his mother and brothers and his disciples, and they stayed there a few days.

So Jesus' brothers advised him, "Leave here and go to Judea so your disciples may see your miracles that you are performing.

(For not even his own brothers believed in him.)

But when his brothers had gone up to the feast, then Jesus himself also went up, not openly but in secret.

Jesus replied, "Do not touch me, for I have not yet ascended to my Father. Go to my brothers and tell them, 'I am ascending to my Father and your Father, to my God and your God.'"

So the saying circulated among the brothers and sisters that this disciple was not going to die. But Jesus did not say to him that he was not going to die, but rather, "If I want him to live until I come back, what concern is that of yours?"
