I Thessalonians 5:28

The notation at the end of I Thessalonians indicating that Paul wrote this epistle from Athens, which was a later addition to the Greek text, is contradicted by the internal evidence. Paul was alone during the entire time he was in Athens. Silas and Timothy did not join him until Paul was in Corinth: “Now when Silas and Timothy came down from Macedonia…” (Acts 18:5). In writing to the Thessalonians, Paul begins his epistle with this opening; “Paul and Silvanus and Timothy, to the church of the Thessalonians, which is in God the Father and the Lord Jesus Christ” (I Thes. 1:1). Since Silas and Timothy joined Paul at Corinth, the internal evidence indicates that this epistle was written from Corinth, rather than from Athens.
