(6) 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.
(6) The apostle expounding the commandment of charity towards one another, tells first that when he urges holiness, he brings no new idea of life (as they use to do who devise traditions one after another) but reminds them of that same law which God gave in the beginning, that is, by Moses, at the time that God began to make laws for his people.
