Col 2:1  For I would that ye knew what great conflict I have for you, and for them at Laodicea, and for as many as have not seen my face in the flesh; 

Col 4:16  And when this epistle is read among you, cause that it be read also in the church of the Laodiceans; and that ye likewise read the epistle from Laodicea*. 

*Note. Paul's first letter to Timothy was written from Laodicea
