{Luke, the beloved physician} (Loukas ho iatros ho
agap(8874)os). Mentioned also in  Phm 1:24  2Ti 4:11 . The author of
the Gospel and the Acts. Both Mark and Luke are with Paul at this
time, possibly also with copies of their Gospels with them. The
article here (repeated) may mean "my beloved physician." It would
seem certain that Luke looked after Paul's health and that Paul
loved him. Paul was Luke's hero, but it was not a one-sided
affection. It is beautiful to see preacher and physician warm
friends in the community. {Demas} (D(886d)as). Just his name here
(a contraction of Demetrius), but in  2Ti 4:10  he is mentioned
as one who deserted Paul.
