Two things especially are observable in this account of the posterity of Shem: -

I.The description of Shem, Gen 10:21. We have not only his name, Shem, which signifies a name, but two titles to distinguish him by: -

1.He was the father of all the children of Eber. Eber was his great grandson; but why should he be called the father of all his children, rather than of all Arphaxad's, or Salah's, etc.? Probably because Abraham and his seed, God's covenant-people, not only descended from Heber, but from him were called Hebrews; Gen 14:13, Abram the Hebrew. Paul looked upon it as his privilege that he was a Hebrew of the Hebrews, Phi 3:5. Eber himself, we may suppose, was a man eminent for religion in a time of general apostasy, and a great example of piety to his family; and, the holy tongue being commonly called from him the Hebrew, it is probable that he retained it in his family, in the confusion of Babel, as a special token of God's favour to him; and from him the professors of religion were called the children of Eber. Now, when the inspired penman would give Shem an honourable title, he calls him the father of the Hebrews. Though when Moses wrote this, they were a poor despised people, bond-slaves in Egypt, yet, being God's people, it was an honour to a man to be akin to them. As Ham, though he had many sons, is disowned by being called the father of Canaan, on whose seed the curse was entailed (Gen 9:22), so Shem, though he had many sons, is dignified with the title of the father of Eber, on whose seed the blessing was entailed. Note, a family of saints is more truly honourable than a family of nobles, Shem's holy seed than Ham's royal seed, Jacob's twelve patriarchs than Ishmael's twelve princes, Gen 17:20. Goodness is true greatness.

2.He was the brother of Japheth the elder, by which it appears that, though Shem is commonly put first, he was not Noah's first-born, but Japheth was older. But why should this also be put as part of Shem's title and description, that he was the brother of Japheth, since it had been, in effect, said often before? And was he not as much brother to Ham? Probably this was intended to signify the union of the Gentiles with the Jews in the church. The sacred historian had mentioned it as Shem's honour that he was the father of the Hebrews; but, lest Japheth's seed should therefore be looked upon as for ever shut out from the church, he here reminds us that he was the brother of Japheth, not in birth only, but in blessing; for Japheth was to dwell in the tents of Shem. Note, (1.) Those are brethren in the best manner that are so by grace, and that meet in the covenant of God and in the communion of saints. (2.) God, in dispensing his grace, does not go by seniority, but the younger sometimes gets the start of the elder in coming into the church; so the last shall be first and the first last.

II.The reason of the name of Peleg (Gen 10:25): Because in his days (that is, about the time of his birth, when his name was given him), was the earth divided among the children of men that were to inhabit it; either when Noah divided it by an orderly distribution of it, as Joshua divided the land of Canaan by lot, or when, upon their refusal to comply with that division, God, in justice, divided them by the confusion of tongues: whichsoever of these was the occasion, pious Heber saw cause to perpetuate the remembrance of it in the name of his son; and justly may our sons be called by the same name, for in our days, in another sense, is the earth, the church, most wretchedly divided.

Joktan - He had thirteen sons who had their dwelling from Mesha unto Sephar, a mount of the east, which places Calmet supposes to be mount Masius, on the west in Mesopotamia, and the mountains of the Saphirs on the east in Armenia, or of the Tapyrs farther on in Media. In confirmation that all men have been derived from one family, let it be observed that there are many customs and usages, both sacred and civil, which have prevailed in all parts of the world; and that these could owe their origin to nothing but a general institution, which could never have existed, had not mankind been originally of the same blood, and instructed in the same common notions before they were dispersed. Among these usages may be reckoned,

1.The numbering by tens.

2.Their computing time by a cycle of seven days.

3.Their setting apart the seventh day for religious purposes.

4.Their use of sacrifices, propitiatory and eucharistical.

5.The consecration of temples and altars.

6.The institution of sanctuaries or places of refuge, and their privileges.

7.Their giving a tenth part of the produce of their fields, etc., for the use of the altar.

8.The custom of worshipping the Deity bare-footed.

9.Abstinence of the men from all sensual gratifications previously to their offering sacrifice.

10.The order of priesthood and its support.

11.The notion of legal pollutions, defilements, etc.

12.The universal tradition of a general deluge.

13.The universal opinion that the rainbow was a Divine sign, or portent, etc., etc.

See Dodd.

The wisdom and goodness of God are particularly manifested in repeopling the earth by means of three persons, all of the same family, and who had witnessed that awful display of Divine justice in the destruction of the world by the flood, while themselves were preserved in the ark. By this very means the true religion was propagated over the earth; for the sons of Noah would certainly teach their children, not only the precepts delivered to their father by God himself, but also how in his justice he had brought the flood on the world of the ungodly, and by his merciful providence preserved them from the general ruin. It is on this ground alone that we can account for the uniformity and universality of the above traditions, and for the grand outlines of religious truth which are found in every quarter of the world. God has so done his marvellous works that they may be had in everlasting remembrance.

And Ophir, and Havilah, and Jobab,.... If several of the sons of Joktan went into India, as the Arabs say, one would be tempted to think that Ophir in India, whither Solomon sent his ships once in three years, had its name from the first of these; See Gill on Gen 10:26 but as this would be carrying him too far from the rest of his brethren, who appear to have settled in Arabia, some place must be found for him there; and yet there is none in which there is any likeness of the name, unless Coper can be thought to be, a village in the country of the Cinaedocolpites, on the Arabian Gulf, as in Ptolemy (f), or Ogyris, an island in the same sea, Pliny (g) makes mention of the same with the Organa of Ptolemy (h), placed by him on the Sachalite bay; wherefore Bochart (i) looks out elsewhere for a seat for this Ophir, or "Oupheir", as in the Septuagint version, and finding in a fragment of Eupolemus, preserved by Eusebius (k), mention made of the island of Ourphe, which he thinks should be Ouphre, or Uphre, situated in the Red sea, seems willing to have it to be the seat of this man and his posterity, and that it had its name from him; or that their seat was among the Cassanites or Gassandae, the same perhaps with the tribe of Ghassan, Aupher and Chasan signifying much the same, even great abundance and treasure: Havilah, next mentioned, is different from Havilah, the son of Cush, Gen 10:7 and so his country; but it is difficult where to fix him; one would rather think that the Avalite bay, emporium, and people, should take their name from him than from Obal, Gen 10:28 but Bochart (l) chooses to place him and his posterity in Chaulan, a country in Arabia Felix, in the extreme part of Cassanitis, near the Sabaeans: and Jobab, the last of Joktan's sons, was the father of the Jobabites, called by Ptolemy (m) Jobarites, corruptly for Jobabites, as Salmasius and Bochart think; and who are placed by the above geographer near the Sachalites in Arabia Felix, whose country was full of deserts, as Jobab in Arabic signifies, so Bochart (n) observes, as the countries above the Sachalite bay were, by which these Jobabites are placed:

all these were the sons of Joktan; the thirteen before mentioned, all which had their dwelling in Arabia or near it, and which is further described in the following verse.

Peleg; for in his days was the earth divided--After the flood (Gen 11:10-16) the descendants of Noah settled at pleasure and enjoyed the produce of the undivided soil. But according to divine instruction, made probably through Eber, who seems to have been distinguished for piety or a prophetic character, the earth was divided and his son's name, "Peleg," was given in memory of that event (see Deu 32:8; Act 17:26).
