'Brother's' in the Bible

But Herod the Tetrarch, being repeatedly rebuked by him about Herodias his brother's wife, and about all the wicked deeds that he had done,

"And why look at the splinter in your brother's eye instead of giving careful attention to the beam in your own?

How can you say to your brother, 'Brother, let me take that splinter out of your eye,' when all the while you yourself do not see the beam in your own eye? Vain pretender! take the beam out of your own eye first, and then you will see clearly to take the splinter out of your brother's eye.
