and to James the son of Zebedee,and to his brother John,He gave the name “Boanerges”(that is, “Sons of Thunder”);

Whoever does the will of God is My brother and sister and mother.”

He did not let anyone accompany Him except Peter, James, and John, James’s brother.

Isn’t this the carpenter, the son of Mary, and the brother of James, Joses, Judas, and Simon? And aren’t His sisters here with us?” So they were offended by Him.

For Herod himself had given orders to arrest John and to chain him in prison on account of Herodias, his brother Philip’s wife, whom he had married.

“Teacher, Moses wrote for us that if a man’s brother dies, leaves his wife behind, and leaves no child, his brother should take the wife and produce offspring for his brother.

Then brother will betray brother to death, and a father his child. Children will rise up against parents and put them to death.
