 Paul puts, of course, Silas and Timothy. They are mentioned with him. Silas is with him. Silas, of course, travels with Paul on a second missionary journey after there was the strong disagreement with Barnabas over John Mark. We're getting ready to get right into that in the book of Acts. We'll be there probably in just a few weeks covering that disagreement that does take place. Later, we see him writing a letter for Peter. Look over in Acts chapter 15. This was a key man.
