'Brother's' in the Bible

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.
