Thrice I suffered shipwreck.—Again we have a picture of unrecorded sufferings, which we must refer either to the period of his life between his departure from Jerusalem (Acts 9:30) and his arrival at Antioch (Acts 11:26), or to voyages among the islands of the Ægean Sea during his stay at Corinth or at Ephesus, or to that from Ephesus to Cæsarea in Acts 18:22.

A night and a day I have been in the deep.—Taken in their natural sense the words probably point to one of the shipwrecks just mentioned, in which, either swimming or with the help of a plank (as in Acts 27:44), he had kept himself floating for nearly a whole day, beginning with the night. They have, however, been referred by some writers to a dungeon pit, like that into which Jeremiah was cast (Jeremiah 38:6), in which the Apostle was either thrown or hid himself after the stoning at Lystra. Bede (Qucest. iii. 8) relates, on the authority of Archbishop Theodore of Canterbury—whose evidence, as a native of Tarsus, has here a special interest—that there was such a dungeon known by the name of Bythos (the word used here for “deep”) in his time at Cyzicus, and, if so, it is probable enough that the same use of the word may have prevailed in other cities. So at Athens there was a dungeon known as the barathron—a word used also for a “gulf.” On the whole, however, though the conjecture is interesting enough to deserve mention, there seems no adequate reason for adopting it.

Once I was stoned - This was the usual mode of punishment among the Jews for blasphemy. The instance referred to here occurred at Lystra; Acts 14:19. Paley (Horae Paulinae) has remarked that this, when confronted with the history, furnished the nearest approach to a contradiction without a contradiction being actually incurred, that he ever had met with. The history Acts 14:19 contains but one account of his being actually stoned. But prior to this Acts 14:5, it mentions that "an assault was made both of the Gentiles, and also of the Jews with their rulers, to use them despitefully and to stone them, but they were aware of it, and fled to Lystra and Derbe." "Now," Paley remarks, "had the assault been completed; had the history related that a stone was thrown, as it relates that preparations were made both by Jews and Gentiles to stone Paul and his companions; or even had the account of this transaction stopped without going on to inform us that Paul and his companions were aware of their danger and fled, a contradiction between the history and the Epistle would have ensued. Truth is necessarily consistent; but it is scarcely possible that independent accounts, not having truth to guide them, should thus advance to the very brink of contradiction without falling into it."

Thrice I suffered shipwreck - On what occasions, or where, is now unknown, as these instances are not referred to in the Acts of the Apostles. The instance of shipwreck recorded there Acts 27, which occurred when on his way to Rome, happened after this Epistle was written, and should not be supposed to be one of the instances referred to here. Paul made many voyages in going from Jerusalem to Tarsus, and to Antioch, and to various parts of Asia Minor, and to Cyprus; and shipwrecks in those seas were by no means such unusual occurrences as to render this account improbable.

A night and a day ... - The word used here (νυχθήμερον nuchthēmeron) denotes a complete natural day, or 24 hours.

In the deep - To what this refers we do not now certainly know. It is probable, however, that Paul refers to some period when, having been shipwrecked, he was saved by supporting himself on a plank or fragment of the vessel until he obtained relief. Such a situation is one of great peril, and he mentions it, therefore, among the trials which he had endured. The supposition of some commentators that he spent his time on some rock in the deep; or of others that this means some deep dungeon; or of others that he was swallowed by a whale (that is, a big fish), like Jonah, shows the extent to which the fancy is often indulged in interpreting the Bible.

once was I stoned—(Ac 14:19).

thrice … shipwreck—before the shipwreck at Melita (Ac 27:44). Probably in some of his voyages from Tarsus, where he stayed for some time after his conversion, and from which, as being a seafaring place, he was likely to make missionary voyages to adjoining places (Ac 9:30; 11:25; Ga 1:21).

a night and a day … in the deep—probably in part swimming or in an open boat.

once was I stoned. This was at Lystra, at the instigation of the Jews that came from Antioch and Iconium, Acts 14:19 by whom he was left for dead:

thrice I suffered shipwreck; neither of which are mentioned by Luke in the Acts of the Apostles; for the shipwreck he suffered as when he went to Rome was some time after the writing of this epistle, and therefore cannot be one of these here referred to

a night and a day I have been in the deep; some understand this of a well, called "Bythos", or "the deep", which was near Lystra, where the apostle was hid for such a space of time after his deliverance there; but this, were it so, he would scarcely reckon among his very great hardships and sufferings: others of a prison at Cyzicum in Asia, which, because of its very great height, was called "the depth of the sea", in which the apostle was imprisoned for such a time; but, we nowhere read that he ever was at that place, or preached there, and much less was imprisoned there; and had he, it is not likely that he should particularly point out such a short imprisonment, but would have let it pass in the general account of being in prisons before mentioned: but rather this is to be understood of the sea, often called the "deep" in Scripture, where by some accident he was cast, and was in it, as the Syriac version has it, , "where was no ship", or without one, being shipwrecked; or being cast, or having fallen into the sea, he was swimming in it, or was preserved by a broken piece of the ship, or by some other means, or by the wonderful providence of God for so long a time; though as sailing in those times was chiefly by coasting, this phrase may only signify that the ship in which he was was drove from the coast into the sea, and lost sight of the land for the space of a day and night, and lay floating about in the deep, which was reckoned very dangerous. The word "a night day", signifies a whole natural day, consisting of a night and a day; and is an Hebraism, and answers to , "the evening and the morning", which make a full day; see Genesis 1:5 Daniel 8:14.
