To Mark Twain is attributed the comment that the book of Ether is "chloroform in print." Many who read exhaustive genealogies in the Bible can be found dozing as they read. But there must be something to glean from this list of 30 names. The first point to make is that they knew their genealogy and that it was important to them. Under the patriarchal order, this was very significant and the practice continued among the children of Israel as recorded in the Bible.
Second, the names themselves are very significant. We find Jaredite names which later appear in the Old World, i.e. Levi and Aaron, and names which were derived from before Babel, i.e. Seth and Heth, and names which were later adopted by the Mulekites and Nephites, i.e. Corihor (see Ether 7:3). Even the origin of Moroni's name can probably be traced to the Moron (my personal favorite) spoken of in verse 7. The linguistic expert, Hugh Nibley, has expounded for several pages on this very subject. The reader is referred to Lehi in the Desert and the World of the Jaredites, pp. 243-248, 260-261.
