Albert Barnes on 1 John 3:11

For this is the message. Marg., commandment. In the received text, this is αγγελια--a message brought; in several Mss., and in later editions, it is επαγγελια--annunciation, announcement; an order given, or a commandment, Acts 23:21. It is not very material which reading is followed. The word command or rule would express the sense with sufficient clearness. The reference is to the law given by the Savour as a permanent direction to his disciples.

That ye heard from the beginning, that we should love one anther. Jn 13:34, Jn 13:35; 1Jn 2:7.
