Who was the Philippian jailer who guarded Paul and Silas?

The account never names this man; he is simply called the keeper of the prison. Les teaches that he was a Gentile jailer, likely from downtown Philippi, who had probably heard Paul and Silas teach and preach and had probably witnessed their arrest and the beating. He was then given charge over these two men along with all the other prisoners. At midnight Paul and Silas prayed and sang praises unto God, and the prisoners heard them in the dungeon. Suddenly there was a great earthquake, and because God was still working in the economy of miracles and signs and wonders, all the doors were opened and everyone's bands or stocks were loosed. The keeper, awakening and seeing the doors open, drew his sword to kill himself, knowing that if any prisoner escaped the Roman authorities would have killed him anyway, since a jailer paid for an escape with his own life. But Paul cried with a loud voice, telling him to do himself no harm, for they were all still there; he could not be accused of losing a single one. Les points out the little three-letter word "but" — instead of all fleeing, miraculously they all remained, showing a sovereign God at work.
