2 Corinthians 8:22

συνεπέμψαμεν δὲ αὐτοῖς κ. τ. λ.: and we have sent with them our brother, whom we have many times proved earnest in many things, but now much more earnest because of the great confidence which he has in you (cf. Galatians 5:10, πέποιθα εἰς ὑμᾶς), i.e., which was inspired by the account that Titus brought of their good conduct. It is as impossible to identify this “brother” as him of 2 Corinthians 8:18; like the first named he was an envoy of the contributing Churches (2 Corinthians 8:23), and further (what is not said of the first named) he was on terms of personal intimacy with St. Paul, as appears from this verse. The guess that he was Tychicus is a plausible one (see Acts 20:4; Ephesians 6:21; Colossians 4:7; 2 Timothy 4:12; Titus 3:12), but it is only a guess and is incapable of verification. A few cursives (see on 2 Corinthians 13:13) give the name of Barnabas with those of Titus and Luke in the subscription at the end of the Epistle, and this may represent an early tradition.
