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;

in journeyings often, in perils of rivers, in perils of robbers, in perils from my countrymen, in perils from the Gentiles, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren;

In journeying often, in perils of waters, in perils of robbers, in perils from my own nation, in perils from the Gentiles, in perils in the city, in perils in the wilderness, in perils in the sea, in perils from false brethren.

In journeyings often, in perils of waters, in perils of robbers, in perils by my 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;

journeyings many times, perils of rivers, perils of robbers, perils from kindred, perils from nations, perils in city, perils in wilderness, perils in sea, perils among false brethren;

I have served Him by frequent travelling, amid dangers in crossing rivers, dangers from robbers; dangers from my own countrymen, dangers from the Gentiles; dangers in the city, dangers in the Desert, dangers by sea, dangers from spies in our midst;

In frequent travels, in dangers on rivers, in dangers from outlaws, in dangers from my countrymen, in dangers from the Gentiles, in dangers in the town, in dangers in the waste land, in dangers at sea, in dangers among false brothers;

I have made frequent journeys, through dangerous waters, in danger of robbers, in danger from my own nation, in danger from the Gentiles, in danger in the city, in danger in the wilderness, in danger in the sea, in danger from false brothers,

My journeys have been many. I have been through dangers from rivers, dangers from robbers, dangers from my own people, dangers from the Gentiles, dangers in towns, dangers in the country, dangers on the sea, dangers among people pretending to be followers of the Lord.

In journeyings often - Of course subject to the fatigue, toil, and danger which such a mode of life involves.
In perils of waters - In danger of losing my life at sea, or by floods, or by crossing streams.
Of robbers - Many of the countries, especially Arabia, through which he traveled, were then infested, as they are now, with robbers. It is not impossible or improbable that he was often attacked and his life endangered. It is still unsafe to travel in many of the places through which he traveled.
By mine own countrymen - The Jews. They often scourged him; laid wait for him and were ready to put him to death. They had deep enmity against him as an apostate, and he was in constant danger of being put to death by them.
By the pagan - By those who had not the true religion. Several instances of his danger from this quarter are mentioned in the Acts .
In the city - In cities, as in Derbe. Lystra, Philippi, Jerusalem, Ephesus, etc.
In the wilderness - In the desert, where he would be exposed to ambushes, or to wild beasts, or to hunger and want. Instances of this are not recorded in the Acts , but no one can doubt that they occurred, The idea here is, that he had met with constant danger wherever he was, whether in the busy haunts of people or in the solitude and loneliness of the desert.
In the sea - see 2-Corinthians 11:25.
Among false brethren - This was the crowning danger and trial to Paul, as it is to all others. A man can better bear danger by land and water, among robbers and in deserts, than he can bear to have his confidence abused, and to be subjected to the action and the arts of spies upon his conduct. Who these were he has not informed us. He mentions it as the chief trial to which he had been exposed, that he had met those who pretended to be his friends, and who yet had sought every possible opportunity to expose and destroy him. Perhaps he has here a delicate reference to the danger which he apprehended from the false brethren in the church at Corinth.

In journeyings often - He means the particular journeys which he took to different places, for the purpose of propagating the Gospel.
In perils of waters - Exposed to great dangers in crossing rivers; for of rivers the original, ποταμων, must be understood.
Of robbers - Judea itself, and perhaps every other country, was grievously infested by banditti of this kind; and no doubt the apostle in his frequent peregrinations was often attacked, but, being poor and having nothing to lose, he passed unhurt, though not without great danger.
In perils by mine own countrymen - The Jews had the most rooted antipathy to him, because they considered him an apostate from the true faith, and also the means of perverting many others. There are several instances of this in the Acts; and a remarkable conspiracy against his life is related, Acts 23:12, etc.
In perils by the heathen - In the heathen provinces whither he went to preach the Gospel. Several instances of these perils occur also in the Acts.
In perils in the city - The different seditions raised against him; particularly in Jerusalem, to which Ephesus and Damascus may be added.
Perils in the wilderness - Uninhabited countries through which he was obliged to pass in order to reach from city to city. In such places it is easy to imagine many dangers from banditti, wild beasts, cold, starvation, etc.
Perils in the sea - The different voyages he took in narrow seas, such as the Mediterranean, about dangerous coasts, and without compass.
False brethren - Persons who joined themselves to the Church, pretending faith in Christ, but intending to act as spies, hoping to get some matter of accusation against him. He no doubt suffered much also from apostates.

In journeying often,.... Through several countries and kingdoms to preach the Gospel, as he did from Jerusalem round about to Illyricum:
in perils of waters; by the floods being out, which made it very troublesome and dangerous travelling, especially to persons on foot, as was the case of our apostle:
in perils of robbers; for though he had seldom much to lose, yet was in danger of being ill used, and of his life being taken away by such ruffians:
in perils by my own countrymen; the Jews, who bore an implacable hatred to him, because of the doctrines of grace he preached, in opposition to the works of the law of Moses, whether moral or ceremonial; and who generally were concerned in stirring up the Gentiles against him wherever he came:
in perils by the Heathen; the Gentiles, who were incensed against him for inveighing against their idols and idolatrous worship, and other wicked and enormous practices they were addicted to; particularly at Ephesus, by the means of Demetrius the shrine maker, Acts 19:23,
in perils in the city; in any and every city he came into; for bonds and affliction abode him everywhere, as at Jerusalem, Damascus, Antioch, Ephesus, Philippi, Thessalonica, &c.
in perils in the wilderness; by robbers and wild beasts, through hunger and thirst, and by the sands in hurricanes and tempests; though this may be understood not strictly of desert places, but of the country in distinction from the city; See Gill on Matthew 3:1 where travelling is difficult and dangerous, and the people more rustic and uncivil: the phrase, , "in perils of the wildernesses", is a Rabbinical one (p); as is also , "peril in the sea" (q), next mentioned:
in perils in the sea; not only by shipwreck, but through pirates, and the ill usage of mariners, want of provisions, &c.
in perils among false brethren; who pretended to be Christians, but "judaized", teaching the necessity of observing circumcision, and other ceremonies of the law, in order to salvation; these, as the apostle always warmly opposed, so they were sworn enemies to him, and ever sought to do him what mischief they could.
(p) Sepher Cosri, fol. 296. 2. (q) Sepher Cosri, fol. 297. 2.

In--rather, "By": connected with 2-Corinthians 11:23, but now not with "in," as there, and as in 2-Corinthians 11:27, where again he passes to the idea of surrounding circumstances or environments [ALFORD, ELLICOTT and others].
waters--rather, as Greek, "rivers," namely, perils by the flooding of rivers, as on the road often traversed by Paul between Jerusalem and Antioch, crossed as it is by the torrents rushing down from Lebanon. So the traveller Sport lost his life.
robbers--perhaps in his journey from Perga to Antioch in Pisidia. Pisidia was notorious for robbers; as indeed were all the mountains that divided the high land of Asia from the sea.
the heathen--Gentiles.
in the city--Damascus, Acts 9:24-25; Jerusalem, Acts 9:29; Ephesus, Acts 19:23.
false brethren-- (Galatians 2:4).
