Genesis 5:3

“And Adam lived an hundred and thirty years, etc.] The Septuagint version, through mistaken, gives the number two hundred and thirty years: and begat [a son]; not that he had no other children during this time than Cain and Abel; this is only observed to show how old he was when Seth was born, the son here meant; who was begotten in his own likeness, after his image; not in the likeness, and after the image of God, in which Adam was created; for having sinned, he lost that image, at least it was greatly defaced, and he came short of that glory of God, and could not convey it to his posterity; who are, and ever have been conceived in sin, and shapen in iniquity; are polluted and unclean,…”

“- Section V - The Line to Noah - The Line of Sheth 1. ספר sepher “writing, a writing, a book.” 9. קינן qēynān, Qenan, “possessor, or spearsman.” 12. מהללאל mahelal'ēl, Mahalalel, “praise of ‘El.” 15. ירד yerĕd, Jered, “going down.” 21. מתוּשׁלה metûshālach, Methushelach, “man of the missile.” 29. נה noach, Noach, “rest,” נחם nācham “sigh; repent; pity; comfort oneself; be revenged.” 32. שׁם shēm, Shem, “name, fame; related: be high.” חם chām Cham, “hot.” יפת yāpet, Japheth, “spreading; related: spread out.” We now enter upon the third of the larger documents contained in Genesis. The first is a diary, the second is a history, the third a genealogy. The first employs the name אלהים…”

“Seth was born in the 130th year of Adam's life, and probably the murder of Abel was not long before. Many other sons and daughters were born to Adam besides Cain and Abel before this; but no notice is taken of them, because an honourable mention must be made of his name only, in whose loins Christ and the church were. But that which is most observable here concerning Seth, is, that Adam begat him in his own likeness after his image - Adam was made in the image of God; but when he was fallen and corrupted, he begat a son in his own image, sinful and defiled, frail and mortal, and miserable like himself; not only a man like himself, consisting of body and soul; but a sinner like himself,…”

“5:3 just like him—in his very image: The image and likeness of God (see note on 1:26) is preserved in human beings despite sin. Adam’s sinful nature was also carried forward (Rom 5:12-14).”

“am 130, bc 3874 hundred: The chronology differs in the Hebrew Text, the Samaritan, the LXX, and Josephus. The LXX adds 100 years to each of the patriarchs Adam, Seth, Enos, Cainan, Mahalaleel, and Enoch, before the birth of their sons; while they take 20 from the age of Methuselah, and add 6 to that of Lamech Thus the space from the creation to the deluge is made 2,242 years, according to the Vatican copy, but 2,262 by the Alexandrine; and the sum total by Josephus is 2,265, by the Samaritan 1,307, and the Hebrew Text, 1,656. The sum total from the Deluge to the 70th year of Terah, according to these authorities, is, Heb. 292; Sam. 942; Sept. Vat. 1,172; Alex. 1,072, and Josephus 1,002. in…”

“As Adam was created in the image of God, so did he beget "in his own likeness, after his image;" that is to say, he transmitted the image of God in which he was created, not in the purity in which it came direct from God, but in the form given to it by his own self-determination, modified and corrupted by sin. The begetting of the son by whom the line was perpetuated (no doubt in every case the first-born), is followed by an account of the number of years that Adam and the other fathers lived after that, by the statement that each one begat (other) sons and daughters, by the number of years that he lived altogether, and lastly, by the assertion "and he died." This apparently superfluous…”
