2 Corinthians 11:26
[In] journeyings often, [in] perils of waters, [in] perils of robbers, [in] perils by [mine own] countrymen, [in] perils by the heathen, [in] perils in the city, [in] perils in the wilderness, [in] perils in the sea, [in] perils among false brethren;
Note 15 at 2Co 11:26: The word "peril" simply means "danger" (American Heritage Dictionary). Paul suffered danger on water, danger from robbers, danger from the Jews, danger from the heathen, danger in the cities and in the wilderness, danger when traveling on the seas, and danger from false brethren.
Note 16 at 2Co 11:26: It is important to remember that Paul was indulging himself in boasting (see note 2 at 2Co 11:1). However, his boasting is still noticeably different than the way most people boast. He was not bragging about his great accomplishments but rather his great sufferings. How many people would list in their bios how many times they had been thrown in prison? Yet Paul gloried in how much he had suffered for the cause of Christ. You can be sure that the false apostles (2Co 11:13) had not boasted in this manner. They had puffed themselves up quite contrarily to the way Paul did.
