Heidegger's Bible Handbook: Ephesians: Subscript

3. The Subscription, that it was written at Rome, and sent by Tychicus.

Thus the Subscription stands: πρὸς Ἐφεσίους ἐγράφη ἀπὸ Ῥώμης διὰ Τυχικοῦ, it was written to the Ephesians at Rome through Tychicus. That it was written at Rome is urged by his express mention of his bonds in Ephesians 4:1; 6:20. And, that Tychicus was the messenger, is not obscurely indicated in Ephesians 6:21, 22.
