'Brother' in the Bible

As Jesus was walking by the Sea of Galilee, He noticed two brothers, Simon who was called Peter, and Andrew his brother, casting a net into the sea; for they were fishermen.

And going on [further] from there He noticed two other brothers, James the son of Zebedee, and his brother John, in the boat with their father Zebedee, mending their nets; and He called them [to follow Him as His disciples].

But I say to you that everyone who continues to be angry with his brother or harbors malice against him shall be guilty before the court; and whoever speaks [contemptuously and insultingly] to his brother, ‘Raca (You empty-headed idiot)!’ shall be guilty before the supreme court (Sanhedrin); and whoever says, ‘You fool!’ shall be in danger of the fiery hell.

So if you are presenting your offering at the altar, and while there you remember that your brother has something [such as a grievance or legitimate complaint] against you,

leave your offering there at the altar and go. First make peace with your brother, and then come and present your offering.

Or how can you say to your brother, ‘Let me get the speck out of your eye,’ when there is a log in your own eye?

Now these are the names of the twelve apostles (special messengers, personally chosen representatives): first, Simon, who is called Peter, and Andrew, his brother; James the son of Zebedee, and John his brother;

“Brother will betray brother to death, and the father his child; and children will rise up and rebel against their parents and cause them to be put death.

For whoever does the will of My Father who is in heaven [by believing in Me, and following Me] is My brother and sister and mother.”

For Herod had John arrested and bound him and put him in prison [at the fortress of Machaerus, east of the Jordan, to keep him away] because of Herodias, the wife of his brother Philip,

Six days later Jesus took with Him Peter and James and John the brother of James, and led them up on a high mountain by themselves.

“If your brother sins, go and show him his fault in private; if he listens and pays attention to you, you have won back your brother.

Then Peter came to Him and asked, “Lord, how many times will my brother sin against me and I forgive him and let it go? Up to seven times?”

My heavenly Father will also do the same to [every one of] you, if each of you does not forgive his brother from your heart.”

saying, “Teacher, Moses said, ‘If a man dies, leaving no children, his brother as next of kin shall marry his widow, and raise children for his brother.’

Now there were seven brothers among us; the first married and died, and having no children left his wife to his brother.
