Ephesians 6:22

Whom I have sent - for the same purpose - Namely, that the Ephesians might know his affairs, and those of the Church at Rome: messengers of this kind frequently passed between the Churches in those ancient times.

Comfort your hearts - By showing you how powerfully he was upheld in all his tribulations, and how God turned his bonds to the furtherance of the Gospel. This must have been great consolation to all the followers of God; and particularly to those in Ephesus or Laodicea, or to whomsoever the epistle was directed. The question, To whom was it sent? is divided between the Ephesians and the Laodiceans. Dr. Lardner has argued strongly in favor of the former; Dr. Paley not less so in favor of the latter.

Whom I have sent unto you - The churches where Paul had preached, would feel a great interest in his welfare. He was a prisoner at Rome, and it was doubtful what the result would be. In this situation, he felt it proper to despatch a special messenger to give information about his condition; to state what was doing in Rome; to ask the prayers of the churches; and to administer consolation to them in their various trials. The same sentiment in regard to the embassy of Tychicus, is expressed in the Epistle to the Colossians, Colossians 4:7-8. No small part of the consolation which he would impart to them would be found in these invaluable letters which he bore to them from the apostle.

6:22 That he might comfort your hearts - By relating the supports I find from God, and the success of the gospel.
