'Brother's' in the Bible

Then the Lord said to Cain, “Where is your brother Abel?”“I don’t know,” he replied. “Am I my brother’s guardian?”

Then He said, “What have you done? Your brother’s blood cries out to Me from the ground!

So now you are cursed, alienated, from the ground that opened its mouth to receive your brother’s blood you have shed.

and stay with him for a few days until your brother’s anger subsides—

until your brother’s rage turns away from you and he forgets what you have done to him. Then I will send for you and bring you back from there. Why should I lose you both in one day?”

Then Judah said to Onan, “Sleep with your brother’s wife. Perform your duty as her brother-in-law and produce offspring for your brother.”

But Onan knew that the offspring would not be his, so whenever he slept with his brother’s wife, he released his semen on the ground so that he would not produce offspring for his brother.

You are not to have sexual intercourse with your brother’s wife; it will shame your brother.

If a man marries his brother’s wife, it is impurity. He has shamed his brother; they will be childless.

“If you see your brother’s ox or sheep straying, you must not ignore it; make sure you return it to your brother.

If you see your brother’s donkey or ox fallen down on the road, you must not ignore it; you must help him lift it up.

But if the man doesn’t want to marry his sister-in-law, she must go to the elders at the city gate and say, ‘My brother-in-law refuses to preserve his brother’s name in Israel. He isn’t willing to perform the duty of a brother-in-law for me.’

then his sister-in-law will go up to him in the sight of the elders, remove his sandal from his foot, and spit in his face. Then she will declare, ‘This is what is done to a man who will not build up his brother’s house.’

One day when Job’s sons and daughters were eating and drinking wine in their oldest brother’s house,

He was still speaking when another messenger came and reported: “Your sons and daughters were eating and drinking wine in their oldest brother’s house.

Don’t abandon your friend or your father’s friend,and don’t go to your brother’s housein your time of calamity;better a neighbor nearby than a brother far away.

In the womb he grasped his brother’s heel,and as an adult he wrestled with God.

I will overturn royal thrones and destroy the power of the Gentile kingdoms. I will overturn chariots and their riders. Horses and their riders will fall, each by his brother’s sword.

Why do you look at the speck in your brother’s eye but don’t notice the log in your own eye?

Hypocrite! First take the log out of your eye, and then you will see clearly to take the speck out of your brother’s eye.

John had been telling Herod, “It is not lawful for you to have your brother’s wife!”

But Herod the tetrarch, being rebuked by him about Herodias, his brother’s wife, and about all the evil things Herod had done,

“Why do you look at the speck in your brother’s eye, but don’t notice the log in your own eye?

Or how can you say to your brother, ‘Brother, let me take out the speck that is in your eye,’ when you yourself don’t see the log in your eye? Hypocrite! First take the log out of your eye, and then you will see clearly to take out the speck in your brother’s eye.

Therefore, let us no longer criticize one another. Instead decide never to put a stumbling block or pitfall in your brother’s way.

unlike Cain, who was of the evil one and murdered his brother. And why did he murder him? Because his works were evil, and his brother’s were righteous.
