Genesis 5:6

“And Seth lived an hundred and five years, and begat Enos.] Not that this was his firstborn, no doubt but he had other children before this time; but this is only mentioned, because it carried the lineage and descent directly from Adam to Noah, the father of the new world, and from whom the Messiah was to spring; whose genealogy to give is a principal view of this book, or account of generations from Adam to Noah.”

There is nothing observable concerning any of those particularly, tho' we have reason to think they were men of eminency, both for prudence and piety: But in general, observe how largely and expressly their generations are recorded. We are told how long they lived that lived in God's fear, and when they died, that died in his favour; but as for others it is no matter: the memory of the just is blessed, but the name of the wicked shall rot. That which is especially observable, is, that they all lived very long; not one of them…”
