We have here a genealogy, not an endless genealogy, for here it ends in Abram, the friend of God, and leads further to Christ, the promised seed, who was the son of Abram, and from Abram the genealogy of Christ is reckoned (Mat 1:1, etc.); so that put ch. 5, ch. 11, and Mt. 1, together, and you have such an entire genealogy of Jesus Christ as cannot be produced, for aught I know, concerning any person in the world, out of his line, and at such a distance from the fountain-head. And, laying these three genealogies together, we shall find that twice ten, and thrice fourteen, generations or descents, passed between the first and second Adam, making it clear concerning Christ that he was not only the Son of Abraham, but the Son of man, and the seed of woman. Observe here, 1. Nothing is left upon record concerning those of this line but their names and ages, the Holy Ghost seeming to hasten through them to the story of Abram. How little do we know of those that have gone before us in this world, even those that lived in the same places where we live, as we likewise know little of those that are our contemporaries in distant places! we have enough to do to mind the work of our own day, and let God alone to require that which is past, Ecc 3:15. 2. There was an observable gradual decrease in the years of their lives. Shem reached to 600 years, which yet fell short of the age of the patriarchs before the flood; the next three came short of 500; the next three did not reach to 300; after them we read not of any that attained to 200, except Terah; and, not many ages after this, Moses reckoned seventy, or eighty, to be the utmost men ordinarily arrive at. When the earth began to be replenished, men's lives began to shorten; so that the decrease is to be imputed to the wise disposal of Providence, rather than to any decay of nature. For the elect's sake, men's days are shortened; and, being evil, it is well they are few, and attain not to the years of the lives of our fathers, Gen 47:9. 3. Eber, from whom the Hebrews were denominated, was the longest-lived of any that was born after the flood, which perhaps was the reward of his singular piety and strict adherence to the ways of God.

These are the generations of Shem - This may he called the holy family, as from it sprang Abraham, Isaac, Jacob, the twelve patriarchs, David, Solomon, and all the great progenitors of the Messiah.

We have already seen that the Scripture chronology, as it exists in the Hebrew text, the Samaritan, the Septuagint, Josephus, and some of the fathers, is greatly embarrassed; and it is yet much more so in the various systems of learned and unlearned chronologists. For a full and rational view of this subject, into which the nature of these notes forbids me farther to enter, I must refer my reader to Dr. Hales's laborious work, "A New Analysis of Sacred Chronology," vol. ii., part 1, etc., in which he enters into the subject with a cautious but firm step; and, if he has not been able to remove all its difficulties, has thrown very considerable light upon most parts of it.

These are the generations of Shem,.... Or a genealogy of the posterity of Shem; not of all of them, only of those of the line which led to Abraham, by which might appear the true line in which the Messiah from Adam through Abraham sprung:

Shem was one hundred years old, and begat Arphexad two years after the flood; by which it is pretty plain that he was younger than Japheth; See Gill on Gen 10:21 of Arphaxad his son; see Gill on Gen 10:22.

confound their language--literally, "their lip"; it was a failure in utterance, occasioning a difference in dialect which was intelligible only to those of the same tribe. Thus easily by God their purpose was defeated, and they were compelled to the dispersion they had combined to prevent. It is only from the Scriptures we learn the true origin of the different nations and languages of the world. By one miracle of tongues men were dispersed and gradually fell from true religion. By another, national barriers were broken down--that all men might be brought back to the family of God.
