'Brother' in the Bible

One day, passing along the shore of the Lake of Galilee, He saw Simon and Andrew, Simon's brother, throwing their nets in the Lake; for they were fisherman.

Going on a little further He saw James the son of Zabdi and his brother John: they also were in the boat mending the nets, and He immediately called them.

James the son of Zabdi and John the brother of James (these two He surnamed Boanerges, that is 'Sons of Thunder')

"Here are my mother and my brothers. For wherever there is one who has been obedient to God, there is my brother--my sister--and my mother."

Is not this the carpenter, Mary's son, the brother of James and Joses, Jude and Simon? And do not his sisters live here among us?" So they turned angrily away.

For Herod himself had sent and had had John arrested and had kept him in prison in chains, for the sake of Herodias, his brother Philip's wife; because he had married her.

"Rabbi," they said, "Moses made it a law for us: 'If a man's brother should die and leave a wife, but no child, the man shall marry the widow and raise up a family for his brother.'

"Brother will betray brother to be killed, and fathers will betray children; and children will rise against their parents and have them put to death.
