Unlike Rome, at least we know that he was in Jerusalem.
Concerning 1 Peter 5:13 "her that is in Babylon"; excerpts (note particularly the last one) from Edersheim 'The Life And Times Of Jesus The Messiah', Book 1, Chapter 1,THE JEWISH WORLD IN THE DAYS OF CHRIST -
THE JEWISH DISPERSION IN THE EAST
"...Nor were such the feelings of
the Palestinian Jews only.
These indeed were now a minority. The majority of the nation constituted what was known as the dispersion; a term which, however, no longer expressed its original meaning of banishment by the judgment of God,
12 since
absence from Palestine was now entirely voluntary. But all the more that it referred not to outward suffering,
13 did its continued use indicate a deep feeling of religious sorrow, of social isolation, and of political strangership
14 in the midst of a heathen world. For although,
as Josephus reminded his countrymen,15 there was ‘no nation in the world which had not among them part of the Jewish people,’ since it was ‘widely dispersed over all the world among its inhabitants,’
16 yet they had nowhere found a real home...."
"...
Philo tells its deepest ground, and that of Israel’s loneliness in the heathen world, when speaking, like the others,
of his countrymen as in ‘all the cities of Europe, in the provinces of Asia and in the islands,’ he describes them as, wherever sojourning, having but one metropolis - not Alexandria, Antioch, or Rome - but ‘the Holy City with its Temple, dedicated to the Most High God.’21 A nation, the vast majority of which was dispersed over the whole inhabited earth, had ceased to be a special, and become a world-nation.22 Yet its heart beat in Jerusalem, and thence the life-blood passed to its most distant members. And this, indeed, if we rightly understand it, was the grand object of the ‘Jewish dispersion’ throughout the world...."
"...Far other was the estimate in which the Babylonians were held by the leaders of Judaism. Indeed, according to one view of it,
Babylonia, as well as ‘Syria’ as far north as Antioch, was regarded as forming part of the land of Israel.
30 Every other country was considered outside ‘the land,’ as Palestine was called, with the exception of Babylonia, which was reckoned as part of it.
31 For Syria and Mesopotamia, eastwards to the banks of the Tigris, were supposed to have been in the territory which King David had conquered, and this made them ideally for ever like the land of Israel. But
it was just between the Euphrates and the Tigris that the largest and wealthiest settlements of the Jews were, to such extent that a later writer actually designated them ‘the land of Israel.’ Here
Nehardaa, on the
Nahar Malka, or royal canal, which passed from the Euphrates to the Tigris, was the oldest Jewish settlement. It boasted of a Synagogue, said to have been built by King Jechoniah with stones that had been brought from the Temple.
32 In this fortified city the
vast contributions intended for the Temple were deposited by the Eastern Jews, and thence conveyed to their destination under escort of thousands of armed men. Another of these Jewish treasure-cities was Nisibis, in northern Mesopotamia. Even the fact that wealth, which must have sorely tempted the cupidity of the heathen, could be safely stored in these cities and transported to Palestine, shows how large the Jewish population must have been, and how great their general influence.
In general,
it is of the greatest importance to remember in regard to this Eastern dispersion, that only a minority of the Jews, consisting in all of about 50,000, originally returned from Babylon, first under Zerubbabel and afterwards under Ezra.
33 Nor was their inferiority confined to numbers.
The wealthiest and most influential of the Jews remained behind. According to Josephus,
34 with whom Philo substantially agrees, vast numbers, estimated at millions, inhabited the Trans-Euphratic provinces. To judge even by the number of those slain in popular risings (50,000 in Seleucia alone
35), these figures do not seem greatly exaggerated.
A later tradition had it, that so dense was the Jewish population in the Persian Empire, that Cyrus forbade the further return of the exiles, lest the country should be depopulated.
36 So large and compact a body soon became a political power. Kindly treated under the Persian monarchy, they were, after the fall of that empire,
37 favoured by the successors of Alexander. When in turn the Macedono-Syrian rule gave place to the Parthian Empire,
38 the Jews formed, from their national opposition to Rome, an important element in the East. Such was their influence that, as late as the year 40 a.d., the Roman legate shrank from provoking their hostility.

"...That among such a vast community there should have been poverty, and that at one time, as the Palestinians sneered, learning may have been left to pine in want, we can readily believe. For, as one of the Rabbis had it in explanation of
Deut. xxx. 13: ‘Wisdom is not “beyond the sea” - that is, it will not be found among traders or merchants,’
68 whose mind must be engrossed by gain. And
it was trade and commerce which procured to the Babylonians their wealth and influence, although agriculture was not neglected. Their caravans - of whose camel drivers, by the way, no very flattering account is given69 - carried the rich carpets and woven stuffs of the East, as well as its precious spices, to the West: generally through Palestine to the Phoenician harbours, where a fleet of merchantmen belonging to Jewish bankers and shippers lay ready to convey them to every quarter of the world. These merchant princes were keenly alive to all that passed, not only in the financial, but in the political world. We know that they were in possession of State secrets, and entrusted with the intricacies of diplomacy. Yet, whatever its condition, this Eastern Jewish community was intensely Hebrew. Only eight days’ journey - though, according to Philo’s western ideas of it, by a difficult road
70 - separated them from Palestine; and every pulsation there vibrated in Babylonia. It was in the most outlying part of that colony, in the wide plains of Arabia, that Saul of Tarsus spent those three years of silent thought and unknown labour, which preceded his re-appearance in Jerusalem, when from the burning longing to labour among his brethren, kindled by long residence among these Hebrews of the Hebrews, he was directed to that strange work which was his life’s mission.
71 And it was among the same community that Peter wrote and laboured,
72 amidst discouragements of which we can form some conception from
the sad boast of Nehardaa, that up to the end of the third century it had not numbered among its members any convert to Christianity.73..."
