Ephesians 6:20

Am an ambassador in bonds] RV 'in chains': mg. 'in a chain.' The singular may refer to the coupling-chain by which he could be attached to the soldier that guarded him. In any case, that an ambassador, whose person was inviolate, should be chained, was a paradox.

21, 22. The Mission of Tychicus: almost verbatim as Colossians 4:7, Tychicus is the bearer of both letters, and of that to Philemon: cp. Acts 20:4; 2 Timothy 4:12; Titus 3:12, By long service he well earned the title of 'faithful minister.'

23, 24. Concluding Benediction.

Note the omission of all personal salutations and similar details, of which we have eight vv. in the Epistle to the Colossians. This is a circular letter to several Churches, and hence no individuals are mentioned. Note also the change to the third person, 'to the brethren.. all them that love our Lord.' In Colossians, as elsewhere, he says 'you.' In two other points this benediction differs from that in other letters. It is twofold, not single; Peace be to, Grace be with; and 'Peace' is placed before, not after 'Grace.' Contrast Romans 1:7; 1 Corinthians 1:8; 2 Corinthians 1:2; Galatians 1:3; Colossians 1:2, etc. An imitator would have copied other Epistles.
