'Commandment' in the Bible

No one takes it away from me, but I lay it down of my own free will. I have the authority to lay it down, and I have the authority to take it back again. This commandment I received from my Father."

And I know that his commandment is eternal life. Thus the things I say, I say just as the Father has told me."

"I give you a new commandment -- to love one another. Just as I have loved you, you also are to love one another.

My commandment is this -- to love one another just as I have loved you.
