Who escorted the slave with the letter to Philemon?

The slave who carried the letter to Philemon was Onesimus, and he was accompanied by the Apostle Paul and another companion, likely Tychicus. This letter, known as the Epistle to Philemon, addressed the issue of Onesimus, who had run away from Philemon and sought reconciliation. Paul used the letter to encourage Philemon to receive Onesimus back not just as a slave, but as a beloved brother in Christ.
