Revelation 1:3

he that readeth, and they that hear Plainly the author of the Book, or of this endorsement of it, contemplates its being read publicly in the Church. The apostolic Epistles were thus read, first by the Churches to which they were addressed, then by others in the neighbourhood (Colossians 4:16): even the sub-apostolic Epistles of Clement and Polycarp, and the decidedly post-apostolic one of Soter, Bishop of Rome, were in like manner read in the churches that originally received them, or to which their authors belonged. In the course of the second century, both the Gospels and the apostolic Epistles came to be read in churches generally, as the Law and the Prophets had been read in the synagogues. In the time of Justin Martyr (Apol. I. 67), not to insist on 1 Timothy 5:18; 2 Peter 3:16, it is plain that the New Testament Scriptures were thus recognised as sharing the authority and sanctity of the Old.

and keep those things Attend to them, mindthem. He who reads and they who hear are only blessed if they do this; John 13:17; Matthew 7:25 sq. The word is constantly used of -keeping" the Law, the Commandments, &c., throughout the N. T.: but is commoner in allSt John's writings than in any other.
