Colossians 4:9

He adds, Onesimus, that the embassy may have the more weight. It is, however, uncertain who this Onesimus was. For it can scarcely be believed that this is the slave of Philemon, inasmuch as the name of a thief and a fugitive would have been liable to reproach. (476) He distinguishes both of them by honorable titles, that they may do the more good, and especially Tychicus, who was to exercise the office of an instructor.
