'Commandment' in the Bible

No one takes it from me, but I lay it down {voluntarily}. I have authority to lay it down, and I have authority to take possession of it again. This commandment I received from my Father."

And I know that his commandment is eternal life. So [the things] that I say, just as the Father said to me, thus I say."

"A new commandment I give to you: that you love one another--just as I have loved you, that you also love one another.

This is my commandment: that you love one another just as I have loved you.
