1 Thessalonians 5:27
I charge you by the Lord that this epistle be read unto all the holy brethren.
Note 28 at 1 Th. 5:27: The word "charge" is a strong term in the Greek and carries the idea of a command or even as an oath or vow. Paul is concerned that all receive the information that he has written in this letter.
The Greek word for "read" is used to signify reading aloud. Paul wanted a public reading of this letter to all the believers. Public reading of scripture became an accepted part of worship in the early church (Acts 13:27; 15:21; 2 Cor. 1:13; Eph. 3:4; Col. 4:16).
