But that ye also may know my affairs, [and] how I do,.... Both his temporal and spiritual affairs; as that he was in bonds, and how he was supported under them, and of what use they were to others; how that he preached in his own hired house, and with what success; and what ministering brethren he had with him to assist him; and in what condition was the church at Rome where he now was: the apostle's life and actions would bear the light, and what he did was worthy of imitation, and must be both delightful and useful to know; and the account he sends, by a messenger hereafter named, of whom he gives the following character, that credit might be the more readily given to his relation:Tychicus, a beloved brother, and faithful minister in the Lord,shall make known to you all things.
This Tychicus was of Asia, who accompanied the apostle in his travels, and went with him to Rome, from whence he sent him to several places to relate his case, and to know the state of the churches, Col 4:7.
