'Brother' in the Bible

As he was walking by the Sea of Galilee he saw two brothers, Simon (called Peter) and Andrew his brother, casting a net into the sea (for they were fishermen).

Going on from there he saw two other brothers, James the son of Zebedee and John his brother, in a boat with Zebedee their father, mending their nets. Then he called them.

But I say to you that anyone who is angry with a brother will be subjected to judgment. And whoever insults a brother will be brought before the council, and whoever says 'Fool' will be sent to fiery hell.

So then, if you bring your gift to the altar and there remember that your brother has something against you,

leave your gift there in front of the altar. First go and be reconciled to your brother and then come and present your gift.

Or how can you say to your brother, 'Let me remove the speck from your eye,' while there is a beam in your own?

Now these are the names of the twelve apostles: first, Simon (called Peter), and Andrew his brother; James son of Zebedee and John his brother;

"Brother will hand over brother to death, and a father his child. Children will rise against parents and have them put to death.

For whoever does the will of my Father in heaven is my brother and sister and mother."

For Herod had arrested John, bound him, and put him in prison on account of Herodias, his brother Philip's wife,

Six days later Jesus took with him Peter, James, and John the brother of James, and led them privately up a high mountain.

"If your brother sins, go and show him his fault when the two of you are alone. If he listens to you, you have regained your brother.

Then Peter came to him and said, "Lord, how many times must I forgive my brother who sins against me? As many as seven times?"

So also my heavenly Father will do to you, if each of you does not forgive your brother from your heart."

"Teacher, Moses said, 'If a man dies without having children, his brother must marry the widow and father children for his brother.'

Now there were seven brothers among us. The first one married and died, and since he had no children he left his wife to his brother.
