12 When I send Artemas to you, or Tychicus, be diligent to come to me at Nicopolis, for I have decided to spend the winter there.
13 Send Zenas the lawyer and Apollos on their journey with haste, that they may lack nothing.
14 And let our people also learn to maintain good works, to meet urgent needs, that they may not be unfruitful.
15 All who are with me greet you. Greet those who love us in the faith. Grace be with you all. Amen.
Tychicus (v.12) — Tychicus was a native of the province of Asia and perhaps of Ephesus, Acts 20:4. He accompanied Paul on his return from his third journey, and Paul gave a high commendation of him in Ephesians 6:21 and Colossians 4:7. That he was a companion of the apostle in his imprisonment we may gather from 2 Timothy 4:12. If he was sent to Ephesus at this time, Artemas may have been the one sent to Crete. — Vine, page 247.
be diligent (v.12) = do your best — translated “study” in 2 Timothy 2:15 in the KJV
lawyer (v.13) — probably an expert in Mosaic law
