Boyd’s Bible Dictionary:
(punishment). A city of Phrygia. Paul wrote to the church there (Col. 1:2; 4:13).
Concise Bible Dictionary:
City on the river Lycus in Phrygia, of Asia Minor (Col. 1:2). It appears as though Paul had not visited the city when he wrote the epistle to the church there (Compare Col. 1:7; Col. 2:1); but he may have done so in his journeys or have gone thither from Ephesus. He hoped to visit them soon (Philem. 1:22), for to this place Philemon and Onesimus belonged (Col. 4:9). Colosse had been a place of importance, but declined on the rise of Hierapolis and Laodicea. The modern village Khonas is about three miles distant from the ancient ruins.
