'New Commandment' in the Bible

I give unto a new commandment, That you must love one another with divine love; as I have loved you with divine love, that you must also love one another with divine love:

Beloved, I write no new commandment to you, but the old one which you had from the beginning; the old commandment is the word which you have heard.

Again I do write a new commandment to you, which is true in him and in you: because the darkness is passing away, and the true light is already shining.

And now I entreat thee, O Cyria, not as writing to thee a new commandment, but that which we had from the beginning, that we love one another with divine love.
