BSN: Silas

Silas and Silvanus are different forms of the same name. Luke (Acts 15:22, 32, 34, 40; 16:19, 22, 25, 29; 17:4, 10, 14, 15; 18:5) and the believers in Jerusalem (Acts 15:27) called him Silas, but Paul (2 Cor 1:19; 1 Thess 1:1; 2 Thess 1:1) and Peter (1 Pet 5:12) called him Silvanus. (Similarly, Jude and Judas are different forms of the same name, as are Pricilla and Prisca.)
Silas was a NT gospel worker who labored with both Peter and Paul.
He was a leader among the believers in Jerusalem at the time of the big meeting in Jerusalem about the Gentiles (Acts 15).
After the meeting, Silas returned with Paul to Antioch and continued to work with him after that.
When, at the outset of the “second missionary journey,” Paul and Barnabas parted ways over their disagreement about John Mark (Acts 14:36-41), Silas took the place on Barnabas on Paul’s team.
