ISB ~ 1 Peter 5 v12

Silvanus:Also known in the NT as “Silas”. He was once a member of Paul’s missionary team (Acts 15:40; 2 Cor 1:19) and a co-sender of two of his letters (1 Thess 1:1; 2 Thess 1:1). Most likely, Silvanus is mentioned here because Peter employed him as the writer or drafter of the epistle. It is also possible that he delivered the letter to its original recipients (1 Pet 1:1).
