'Brother' in the Bible

While Jesus was walking beside the Sea of Galilee, he saw Simon and his brother Andrew. They were throwing a net into the sea because they were fishermen.

Going on a little farther, he saw James, the son of Zebedee, and his brother John. They were in a boat repairing their nets.

Zebedee's sons James and his brother John (whom he named Boanerges, that is, Sons of Thunder),

Whoever does the will of God is my brother and sister and mother."

Jesus allowed no one to go further with him except Peter, James, and John, the brother of James.

This is the builder, the son of Mary, and the brother of James, Joseph, Judas, and Simon, isn't it? His sisters are here with us, aren't they?" And they were offended by him.

because Herod himself had sent men who arrested John, bound him with chains, and put him in prison on account of Herodias, his brother Philip's wife, whom Herod had married.

"Teacher, Moses wrote for us that if a man's brother dies and leaves a wife but no child, he should marry the widow and have children for his brother.

Brother will betray brother to death, and a father his child. Children will rebel against their parents and have them put to death.
