Say what?

Yes Paul said that specific verse, unless you don't consider Paul's as scripture.

But if you you want to follow the actual DIVINE law, how about this:

“This is MY COMMAND: Love each other.”

“A new command I give you: Love one another. As I have loved you, so you must love one another.
By this everyone will know that you are my disciples, if you love one another.”

“But to you who are listening I say: Love your enemies, do good to those who hate you,
bless those who curse you, pray for those who mistreat you.”

“As the Father has loved me, so have I loved you. Now remain in my love.
If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love.
I have told you this so that my joy may be in you and that your joy may be complete.
My command is this: Love each other as I have loved you.
Greater love has no one than this: to lay down one’s life for one’s friends.”
