'Love One Another' in the Bible

for this is the injunction which ye heard from the beginning, that we should love one another: not as Cain who was of the evil one, and slew his brother;

And this is his commandment, that we should believe in the name of his Son Jesus Christ, and love one another, as He hath given us a charge to do.

Beloved, let us love one another: for love is from God; and every one that loveth is born of God, and knoweth God.

Beloved, if God so loved us, we ought also to love one another.

No one hath ever seen God: but if we love one another, God dwelleth in us and his love is perfected in us.
