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 Joktan begat Almodad,.... And twelve more mentioned later: the Arabic writers (o) say be had thirty one sons by one woman, but all, excepting two, left Arabia, and settled in India; the Targum of Jonathan adds,"who measured the earth with ropes,''as if he was the first inventor and practiser of geometry: from him are thought to spring the Allumaeotae, a people whom Ptolemy (p) places in Arabia Felix, called so by the Greeks, instead of Almodaei: Mr. Broughton (q) sets Eldimaei over against this man's name, as if they were a people that sprung from him; whereas this word is wrongly put in Ptolemy (r) for Elymaeans, as it is in the Greek text, a people joining to the Persians:

and Sheleph and Hazarmaveth, and Jerah: to the first of these, Sheleph, the Targum of Jonathan adds,"who drew out the water of the rivers;''his people are supposed by Bochart (s), to be the Alapeni of Ptolemy (t), which should be read Salapeni, who were, he says, more remote from the rest, almost as far as the neck of Arabia, and not far from the spring of the river Betius. The next son, Hazarmaveth, or Hasermoth, as in the Vulgate Latin, is thought to give name to a people in Arabia, called by Pliny (u) Chatramotitae, and by Ptolemy Cathramonitae, whose country, Strabo says (w), produces myrrh; according to Ptolemy (x) they reached from the mountain Climax to the Sabaeans, among whom were a people, called, by Pliny (y), Atramitae, who inhabited a place of the same name, and which Theophrastus calls Adramyta, which comes nearer the name of this man, and signifies the court or country of death: and in those parts might be places so called, partly from the unwholesomeness of the air, being thick and foggy, and partly from the frankincense which grew there, which was fatal to those that gathered it, and therefore only the king's slaves, and such as were condemned to die, were employed in it, as Bochart (z) has observed from Arrianus; as also because of the multitude of serpents, with which those odoriferous countries abounded, as the same writer relates from Agatharcides and Pliny. The next son of Joktan is Jerah, which signifies the moon, as Hilal does in Arabic; and Alilat with the Arabians, according to Herodotus (a), is "Urania", or the moon; hence Bochart (b) thinks, that the Jeracheans, the posterity of Jerah, are the Alilaeans of Diodorus Siculus (c), and others, a people of the Arabs; and the Arabic geographer, as he observes, makes mention of a people near Mecca called Bene Hilal, or the children of Jerah; and he is of opinion that the island Hieracon, which the Greeks call the island of the Hawks placed by Ptolemy (d), in Arabia Felix, adjoining to the country which lies upon the Arabian Gulf, is no other than the island of the Jeracheans, the posterity of this man: the Arabs (e) speak of a son of Joktan or Cahtan, they call Jareb, who succeeded his father, which perhaps may be a corruption of Jerah; and another, called by them Jorham.

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).
