Ephesians 6:20 - Coke's Commentary on the Holy Bible

For which I am an ambassador in bonds:— Some would render the original (πρεσβευω εν αλυσει) I grow old in a chain: comp. Philemon 1:9 the phrase where Παυλος πρεσβυτης signifies Paul the aged. But it is certain that the common version of this passage may be justified. As the persons of ambassadors were always sacred, the Apostle seems to refer to the outrage which was done to his divine Master in this violation of his liberty.
