{Was minded to take with them} (ebouleto sunparalabein).
Imperfect middle (ebouleto), not aorist middle ebouleusato of
the Textus Receptus. Barnabas willed, wished and stuck to it
(imperfect tense). Sunparalabein is second aorist active
infinitive of the double compound sunparalamban(935c), old verb to
take along together with, used already about John Mark in  12:25 
and by Paul in  Ga 2:1  about Titus. Nowhere else in the N.T.
Barnabas used the ingressive aorist in his suggestion.
