From Jerusalem (exō Ierousalēm). Probably correct text, though D has apo. Westcott and Hort follow Aleph B in reading eis (to) Jerusalem, an impossible reading contradicted by Act 11:29.; Act 13:1. The ministration (diakonian) referred to is that in Act 11:29. which may have taken place, in point of time, after the death of Herod.
Taking with them (sunparalabontes). Taking along (para) with (sun) them, John Mark from Jerusalem (Act 12:12) to Antioch (Act 13:1). The aorist participle does not express subsequent action as Rackham here argues (Robertson, Grammar, pp. 861-863).
