Silas in the Bible Encyclopedia - ISBE

si'-las (Silas, probably contraction for Silouanos; the Hebrew equivalents suggested are shalish, "Tertius," or shelach (Gen 10:24) (Knowling), or sha'ul = "asked" (Zahn)): The Silas of Acts is generally identified with the Silvaus of the Epistles. His identification with Titus has also been suggested, based on 2 Cor 1:19; 8:23, but this is very improbable (compare Knowling, Expositor's Greek Test., II, 326). Silas, who was probably a Roman citizen (compare Acts 16:37), accompanied Paul during the greater part of his 2nd missionary journey (Acts 15 through 18). At the meeting of the Christian community under James at Jerusalem, which decided that circumcision should not be obligatory in the case of Gentile believers, Silas and Judas Barsabas were appointed along with Paul and Barnabas to convey to the churches in Antioch and Syria and Cilicia the epistle informing them of this decision. As "leading men among the brethren" at Jerusalem, and therefore more officially representative of the Jerusalem church than Paul and Barnabas, Silas and Judas were further commissioned to confirm the contents of the letter by "word of mouth." On arrival at Antioch, the epistle was delivered, and Judas and Silas, "being themselves also prophets, exhorted the brethren with many words, and confirmed them." Their mission being thus completed, the four were "dismissed in peace from the brethren unto those that had sent them forth" (Revised Version), or "unto the apostles" (the King James Version) (Acts 15:22-33). Different readings now render the immediate movements of Silas somewhat obscure; Acts 15:33 would imply that he returned to Jerusalem. But some texts proceed in 15:34, "Notwithstanding it pleased Silas to abide there still," and others add "and Judas alone proceeded." Of this, the first half is accepted by the King James Version. The principal texts however reject the whole verse and are followed in this by the Revised Version (British and American). It is held by some that he remained in Antioch till chosen by Paul (Acts 15:40). Others maintain that he returned to Jerusalem where John Mark then was (compare Acts 13:13); and that either during the interval of "some days" (Acts 15:36), when the events described in Gal 2:11 ff took place (Wendt), he returned to Antioch along with Peter, or that he and John Mark were summoned thither by Paul and Barnabas, subsequent to their dispute regarding Mark.
