'Brother' in the Bible

Passing along by the sea of Galilee, he saw Simon and Andrew the brother of Simon casting a net into the sea, for they were fishermen.

Going on a little further from there, he saw James the son of Zebedee, and John, his brother, who were also in the boat mending the nets.

James the son of Zebedee; John, the brother of James, and he surnamed them Boanerges, which means, Sons of Thunder;

For whoever does the will of God, the same is my brother, and my sister, and mother."

He allowed no one to follow him, except Peter, James, and John the brother of James.

Isn't this the carpenter, the son of Mary, and brother of James, Joses, Judah, and Simon? Aren't his sisters here with us?" They were offended at him.

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

"Teacher, Moses wrote to us, 'If a man's brother dies, and leaves a wife behind him, and leaves no children, that his brother should take his wife, and raise up offspring for his brother.'

"Brother will deliver up brother to death, and the father his child. Children will rise up against parents, and cause them to be put to death.
