Colossians 4:7 - Coke's Commentary on the Holy Bible

All my state shall Tychicus declare— From comparing this verse with Ephesians 6:21-22 where Tychicus is mentioned as sent by St. Paul from Rome to Ephesus, which was not very far from Colosse, it may be very probably inferred, that these two epistles to the Ephesians and Colossians, which contain many similar passages, were written about the same time, and might be sent together.
