Donald Etz says that the Genesis 5 numbers were multiplied by ten by a later editor. These interpretations introduce an inconsistency: it would mean that the ages of the first nine patriarchs at fatherhood, ranging from 62 to 230 years in the manuscripts, would then be transformed into an implausible range such as 5 to years. Others say that the first list, of only 10 names for 1,656 years, may contain generational gaps, which would have been represented by the lengthy lifetimes attributed to the patriarchs. Nineteenth-century critic Vincent Goehlert suggests the lifetimes "represented epochs merely, to which were given the names of the personages especially prominent in such epochs, who, in consequence of their comparatively long lives, were able to acquire an exalted influence".
