Who were the brethren with Paul when he wrote Galatians?
The brethren with Paul when he wrote to the churches of Galatia were his traveling companions. According to the context, this group included Dr. Luke, Timothy, Titus, and other fellow believers who were all in Paul's company at that particular time.
Les explains that the phrase 'all the brethren which are with me' refers to Paul's traveling companions, as seen in the Book of Acts.
