Beloved, I am not writing to you a new commandment, but an old one, which you have had from the beginning. This commandment is the message you have heard.
KJV
Brethren, I write no new commandment unto you, but an old commandment which ye had from the beginning. The old commandment is the word which ye have heard from the beginning.
ASV
Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard.
Then again, I am also writing to you a new commandment, which is true in Him and also in you. For the darkness is fading and the true light is already shining.
KJV
Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.
ASV
Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth.
