Note 19 at 2 Cor. 11:28: Verses 23-27 had listed physical suffering without mention of the things Paul suffered emotionally. Here Paul mentions the care he had for all the churches as an inner suffering. This is not to say that he was oppressed or fearful or defeated (see note 20 at v. 29, below), but that the weight of responsibility Paul felt for those he had led to Christ was a pressure on him that he had to continually cast on the Lord (1 Pet. 5:7).
