'Commandment' in the Bible

No one takes it away from me, but I lay it down by myself. I have power to lay it down, and I have power to take it again. I received this commandment from my Father."

For I spoke not from myself, but the Father who sent me, he gave me a commandment, what I should say, and what I should speak.

I know that his commandment is eternal life. The things therefore which I speak, even as the Father has said to me, so I speak."

A new commandment I give to you, that you love one another, just like I have loved you; that you also love one another.

"This is my commandment, that you love one another, even as I have loved you.
