{And he came also to Derbe and Lystra} (kat(886e)t(8873)en de kai
eis Derb(886e) kai eis Lustran). First aorist active of katanta(935c),
late verb to come down to, to arrive at. He struck Derbe first of
the places in the first tour which was the last city reached
then. {Timothy} (Timotheos). Apparently a native of Lystra
("there," ekei), his Hebrew mother named Eunice and grandmother
Lois ( 2Ti 1:5 ) and his Greek father's name not known. He may
have been a proselyte, but not necessarily so as Timothy was
taught the Scriptures by his mother and grandmother ( 2Ti 3:15 ),
and, if a proselyte, he would have had Timothy circumcised. It is
idle to ask if Paul came on purpose to get Timothy to take Mark's
place. Probably Timothy was about eighteen years of age, a
convert of Paul's former visit a few years before ( 1Ti 1:2 ) and
still young twelve years later ( 1Ti 4:12 ). Paul loved him
devotedly ( 1Ti 1:3  5:23  2Ti 3:15  Php 2:19f. ). It is a
glorious discovery to find a real young preacher for Christ's
work.
