Colossians
King James Version (KJV)

“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.”
King James Version (KJV)
4:16 The epistle from Laodicea - Not to Laodicea. Perhaps some letter had been written to St. Paul from thence.
Col 4:16 Likewise read the [epistle] from Laodicea. The Epistles addressed to these contiguous churches were for each other. Tychicus no doubt bore also a letter to the Laodiceans. Whether that letter was lost, whether it is the Epistle to the Ephesians, or whether the letter was a general letter to the churches of Asia, has been much discussed. My own opinion is that more than one copy of the Ephesian letter was made, one being delivered to the Ephesian church, and the other to the church at Laodicea. Space will not permit of a discussion upon this point.
