"Next day he came upon two of them fighting, and tried to make peace between them. "'Sirs,' he said, 'you are brothers. Why are you wronging each other?'
1 Corinthians 6:5-8
I say this to shame you. Is it so that there is not among you a single wise man, capable of deciding between a man and his brother?

Let brotherly love continue.
1 Peter 3:8
Finally, you should all be harmonious, sympathetic, loving as brothers, tender-hearted, humble-minded;
1 John 3:11-13
For this is the message that you have listened to from the beginning, "WE ARE TO LOVE ONE ANOTHER."
