By these were the isles of the Gentiles divided in their lands; every one after his tongue, after their families, in their nations.

Of these were the isles of the nations divided in their lands, every one after his tongue, after their families, in their nations.

By these were divided the islands of the Gentiles in their lands, every one according to his tongue and their families in their nations.

From these came the distribution of the isles of the nations, according to their lands, every one after his tongue, after their families, in their nations.

By these have the isles of the nations been parted in their lands, each by his tongue, by their families, in their nations.

From these came the nations of the sea-lands, with their different families and languages.

The islands of the Gentiles were divided by these into their regions, each one according to his tongue, and their families in their nations.

Ab istis separatae sunt insulae Gentium secundum terras suas, singulae secundum linguam suam, secundum familias suas, in gentibus suis.

Thus, we have discovered the ancient seats of Japheth, Iapetos - , around the Caspian, the Euxine, the Aegean, and the north of the Mediterranean. From these coastlands they seem to have spread over Europe, northern, western, and southern Asia, and, both by Behring's Straits and the Atlantic, they at length poured into America. So true is it that Japheth was enlarged, and that by them were "the isles of the nations divided."
In their nations. - We here note the characteristics of a nation. First. It is descended from one head. Others may be occasionally grafted on the original stock by intermarriage. But there is a vital union subsisting between all the members and the head, in consequence of which the name of the head is applied to the whole body of the nation. In the case of Kittim and Dodanim we seem to have the national name thrown back upon the patriarchs, who may have themselves been called Keth and Dodan. Similar instances occur in the subsequent parts of the genealogy. Second. A nation has a country or "land" which it calls its own. In the necessary migrations of ancient tribes, the new territories appropriated by the tribe, or any part of it, were naturally called by the old name, or some name belonging to the old country. This is well illustrated by the name of Gomer, which seems to reappear in the Cimmerii, the Cimbri, the Cymri, the Cambri, and the Cumbri. Third. A nation has its own "tongue." This constitutes at once its unity in itself and its separation from others. Many of the nations in the table may have spoken cognate tongues, or even originally the same tongue. Thus, the Kenaanite, Phoenician, and Punic nations had the same stock of languages with the Shemites. But it is a uniform law, that one nation has only one speech within itself. Fourth. A nation is composed of many "families," clans, or tribes. These branch off from the nation in the same manner as it did from the parent stock of the race.

Isles of the Gentiles - Europe, of which this is allowed to be a general epithet. Calmet supposes that it comprehends all those countries to which the Hebrews were obliged to go by sea, such as Spain, Gaul, Italy, Greece, and Asia Minor.
Every one after his tongue - This refers to the time posterior to the confusion of tongues and dispersion from Babel.

By these were the (c) isles of the Gentiles divided in their lands; every one after his tongue, after their families, in their nations.
(c) So do the Jews call all countries which are separated from them by sea, as Greece, Italy etc, which were given to the children of Japheth, of whom came the Gentiles.

By these were the isles of the Gentiles divided in their lands,.... That is, by those sons of Japheth before mentioned; and by "isles" are meant, not countries surrounded with water, for the isles in this sense would not have been sufficient for the posterity of Japheth; nor can it be thought they would leave the continent, where there was room enough for them, and go into islands; and besides must have found it difficult to get there, when shipping and navigation were little known: but it is usual with the Hebrews, of whom Moses, the writer of this history, was, to call all places beyond the Mediterranean sea, or whatsoever they went to by sea, or that were upon the sea coasts, islands, as Greece, Italy, &c. Moreover, the word sometimes signifies countries, as it does in Job 22:30 and so should be rendered here, as it is by some (y), "the countries of the Gentiles"; so called, because in the times of Moses, and at the writing of this history, those countries were inhabited by Heathens and idolaters, strangers to the true religion: and this division was not made at random, and at the pleasure of a rude company of men, but in an orderly regular manner, with the consent, and by the advice and direction of the principal men of those times; and especially it was directed by the wise providence of the most High, who divided to the nations their inheritance, and set the bounds of the people, Deuteronomy 32:8.
everyone after his tongue, after their families, in their nations; this shows, that what is said concerning the division of countries to the sons of Japheth is by way of anticipation; and that, though thus related, was not done till after the confusion of languages, since the partition was made according to the different languages of men; those that were of the same language went and dwelt together, the several nations of them, and the several families in those nations; by which it appears that this was done by consultation, with great care and wisdom, ranging the people according to their tongues; of which nations were formed, and with them were taken the several families they consisted of.
(y) "regiones gentium", Junius & Tremellius, Piscator, Patrick.

the isles of the Gentiles--a phrase by which the Hebrews described all countries which were accessible by sea (Isaiah 11:11; Isaiah 20:6; Jeremiah 25:22). Such in relation to them were the countries of Europe, the peninsula of Lesser Asia, and the region lying on the east of the Euxine. Accordingly, it was in these quarters the early descendants of Japheth had their settlements.

"From these have the islands of the nations divided themselves in their lands;" i.e., from the Japhetites already named, the tribes on the Mediterranean descended and separated from one another as they dwell in their lands, "every one after his tongue, after their families, in their nations." The islands in the Old Testament are the islands and coastlands of the Mediterranean, on the European shore, from Asia Minor to Spain.

The posterity of Japheth were allotted to the isles of the Gentiles, which were solemnly, by lot, after a survey, divided among them, and probably this island of ours among the rest. All places beyond the sea, from Judea, are called isles, Jeremiah 25:22, and this directs us to understand that promise, Isaiah 42:4, the isles shall wait for his law, of the conversion of the Gentiles to the faith of Christ.
