11:25

three times I was beaten with rods: This was a form of punishment often meted out by Roman authorities. The book of Acts mentions only one of the three times Paul received such a beating. It was before he wrote his second letter to the Corinthians. That beating took place at Philippi. (Ac 16:22, 23) He was also beaten by Jews in Jerusalem, but there is no mention of rods being used. (Ac 21:30-32) At any rate, Paul’s audience in Corinth, a Roman colony, surely knew that such beatings were brutal. The humiliating process started with stripping off the victim’s garments. (Compare 1Th 2:2.) A Roman citizen, such as Paul, was supposed to be shielded by law from beatings. That is why Paul informed the Philippian magistrates that they had infringed on his rights.​—See study notes on Ac 16:35, 37.

stoned: Most likely, Paul here refers to the incident at Lystra that is described at Ac 14:19, 20. Stoning was a method of execution mentioned in the Mosaic Law. (Le 20:2) The stoning was likely a mob action involving fanatic Jews and possibly Gentiles. The intent was clearly to kill Paul; in fact, after stoning him, the attackers assumed that he was dead. Such brutal acts as those described in these verses must have left Paul with lasting physical scars.

three times I experienced shipwreck: The Bible vividly describes one shipwreck that Paul experienced, but it occurred after he wrote this letter. (Ac 27:27-44) Paul frequently traveled by sea. (Ac 13:4, 13; 14:25, 26; 16:11; 17:14, 15; 18:18-22, 27) So there were many occasions when such a disaster might have befallen him. Paul is likely referring to the aftermath of one of his shipwrecks when he writes, a night and a day I have spent in the open sea (lit., “in the deep”). Paul may have clung to a piece of wreckage the whole night and day while being tossed on a stormy sea before he was rescued or washed ashore. Yet, such dire events never stopped him from continuing his travels by sea.
