Wood, a prominent member of the church at Jerusalem; also called Silvanus. He and Judas, surnamed Barsabas, were chosen by the church there to accompany Paul and Barnabas on their return to Antioch from the council of the apostles and elders (Acts 15:22), as bearers of the decree adopted by the council. He assisted Paul there in his evangelistic labours, and was also chosen by him to be his companion on his second missionary tour (Acts 16:19-24). He is referred to in the epistles under the name of Silvanus (2 Cor. 1:19; 1 Thess. 1:1; 2 Thess. 1:1; 1 Pet. 5:12). There is no record of the time or place of his death.
Silas
Silas was a trusted companion of Paul. After Paul and Barnabas parted ways, “Paul chose Silas, and departed,” going through Syria and Cilicia to strengthen the churches. When trouble forced Paul out of Berea, he sent word for Silas and Timothy to join him in Athens. Paul’s letters name him Silvanus, and he shares the greeting at the start of 1 Thessalonians. Peter, too, calls Silvanus “a faithful brother” and says he wrote his letter by him. Readers meet him first in Acts 15, then follow the journeys that come after.
