This chapter and many that follow it repeat the genealogies we have hitherto met with in the sacred history, and put them all together, with considerable additions. We may be tempted, it may be, to think it would have been well if they had not been written, because, when they come to be compared with other parallel places, there are differences found, which we can scarcely accommodate to our satisfaction; yet we must not therefore stumble at the word, but bless God that the things necessary to salvation are plain enough. And since the wise God has thought fit to write these things to us, we should not pass them over unread. All scripture is profitable, though not all alike profitable; and we may take occasion for good thoughts and meditations even from those parts of scripture that do not furnish so much matter for profitable remarks as some other parts. These genealogies, 1. Were then of great use, when they were here preserved, and put into the hands of the Jews after their return from Babylon; for the captivity, like the deluge, had put all into confusion, and they, in that dispersion and despair, would be in danger of losing the distinctions of their tribes and families. This therefore revives the ancient landmarks even of some of the tribes that were carried captive into Assyria. Perhaps it might invite the Jews to study the sacred writings which had been neglected, to find the names of their ancestors, and the rise of their families in them. 2. They are still of some use for the illustrating of the scripture-story, and especially for the clearing of the pedigrees of the Messiah, that it might appear that our blessed Saviour was, according to the prophecies which went before of him, the son of David, the son of Judah, the son of Abraham, the son of Adam. And, now that he has come for whose sake these registers were preserved, the Jews since have so lost all their genealogies that even that of the priests, the most sacred of all, is forgotten, and they know not of any one man in the world that can prove himself of the house of Aaron. When the building is reared the scaffolds are removed. When the promised Seed has come the line that was to lead to him is broken off. In this chapter we have an abstract of all the genealogies in the book of Genesis, till we come to Jacob. I. The descents from Adam to Noah and his sons, out of Gen. 5, (Ch1 1:1-4). II. The posterity of Noah's sons, by which the earth was repeopled, out of Gen. 10, (v. 5-23). III. The descents from Shem to Abraham, out of Gen. 11, (Ch1 1:24-28). IV. The posterity of Ishmael, and of Abraham's sons by Keturah, out of Gen. 25, (Ch1 1:29-35). V. The posterity of Esau, out of Gen. 36, (v. 36-54). These, it is likely, were passed over lightly in Genesis; and therefore, according to the law of the school, we are made to go over that lesson again which we did not learn well.
