'Brotherly' in the Bible

Thus saith the LORD; For three transgressions of Tyrus, and for four, I will not turn away the punishment thereof; because they delivered up the whole captivity to Edom, and remembered not the brotherly covenant:

Be kindly affectioned one to another with brotherly love; in honour preferring one another;

But as touching brotherly love ye need not that I write unto you: for ye yourselves are taught of God to love one another.

Let brotherly love continue.

And to godliness brotherly kindness; and to brotherly kindness charity.
