This verse was evidently not a part of the original text (it is omitted or placed in the margin by New English Bible, Jerusalem Bible, Moffatt, An American Translation*, Phillips, Barclay), and it has been placed in brackets by the Good News Translation. Apparently verse 34 was added by some scribe on the assumption that verse 40 makes it impossible to conclude that Paul went to Jerusalem to get Silas or sent a message for him to come to Antioch. However, this assumption is without foundation, and the addition of verse 34 contradicts the plain meaning of verse 33.
