{And again} (kai palin). This would have been the second
benefit or joy. But he changed his plans and did not make that
trip directly to Corinth, but came on to Macedonia first ( Ac
19:21  20:1f.  1Co 16:2  2Co 2:12 ). {To be set forward by you}
(huph' hum(936e) propemphth(886e)ai). First aorist passive infinitive
of propemp(935c). Paul uses this same verb in  Ro 15:24  for the
same service by the Roman Christians on his proposed trip to
Spain. The Corinthians, especially the anti-Pauline party, took
advantage of Paul's change of plans to criticize him sharply for
vacillation and flippancy. How easy it is to find fault with the
preacher! So Paul has to explain his conduct.
