'Brotherly' in the Bible

As for brotherly love, be affectionate to one another; in matters of worldly honour, yield to one another.

And let us bestow thought on one another with a view to arousing one another to brotherly love and right conduct;

Let brotherly love always continue.

Now that, through your obedience to the truth, you have purified your souls for cherishing sincere brotherly love, you must love another heartily and fervently.

along with power of endurance, godliness; along with godliness, brotherly affection; and along with brotherly affection, love.
