12 "This is my commandment, that you love one another, even as I have loved you.
A new commandment I give to you, that you love one another, just like I have loved you; that you also love one another.
And above all things be earnest in your love among yourselves, for love covers a multitude of sins.
This commandment we have from him, that he who loves God should also love his brother.
In love of the brothers be tenderly affectionate one to another; in honor preferring one another;
and the Lord make you to increase and abound in love one toward another, and toward all men, even as we also do toward you,
But concerning brotherly love, you have no need that one write to you. For you yourselves are taught by God to love one another,
Finally, be all like-minded, compassionate, loving as brothers, tenderhearted, courteous,
Brothers, I write no new commandment to you, but an old commandment which you had from the beginning. The old commandment is the word which you heard from the beginning. Again, I write a new commandment to you, which is true in him and in you; because the darkness is passing away, and the true light already shines. He who says he is in the light and hates his brother, is in the darkness even until now. He who loves his brother remains in the light, and there is no occasion for stumbling in him.
For this is the message which you heard from the beginning, that we should love one another; unlike Cain, who was of the evil one, and killed his brother. Why did he kill him? Because his works were evil, and his brother's righteous. Don't be surprised, my brothers, if the world hates you. We know that we have passed out of death into life, because we love the brothers. He who doesn't love his brother remains in death. Whoever hates his brother is a murderer, and you know that no murderer has eternal life remaining in him. By this we know love, because he laid down his life for us. And we ought to lay down our lives for the brothers. But whoever has the world's goods, and sees his brother in need, and closes his heart of compassion against him, how does the love of God remain in him? My little children, let's not love in word only, neither with the tongue only, but in deed and truth.
We are bound to always give thanks to God for you, brothers,{The word for "brothers" here and where context allows may also be correctly translated "brothers and sisters" or "siblings."} even as it is appropriate, because your faith grows exceedingly, and the love of each and every one of you towards one another abounds;

Commentary on John 15 Matthew Henry Commentary
Chapter 15
It is generally agreed that Christ's discourse in this and the next chapter was at the close of the last supper, the night in which he was betrayed, and it is a continued discourse, not interrupted as that in the foregoing chapter was; and what he chooses to discourse of is very pertinent to the present sad occasion of a farewell sermon. Now that he was about to leave them,
Jhn 15:1-8
Here Christ discourses concerning the fruit, the fruits of the Spirit, which his disciples were to bring forth, under the similitude of a vine. Observe here,
Jhn 15:9-17
Christ, who is love itself, is here discoursing concerning love, a fourfold love.
To induce them to keep his commandments, he urges,
Jhn 15:18-25
Here Christ discourses concerning hatred, which is the character and genius of the devil's kingdom, as love is of the kingdom of Christ. Observe here,
Jhn 15:26-27
Christ having spoken of the great opposition which his gospel was likely to meet with in the world, and the hardships that would be put upon the preachers of it, lest any should fear that they and it would be run down by that violent torrent, he here intimates to all those that were well-wishers to his cause and interest what effectual provision was made for supporting it, both by the principal testimony of the Spirit (v. 26), and the subordinate testimony of the apostles (v. 27), and testimonies are the proper supports of truth.
