Verses 1–8
GENESIS - CHAPTER FIVE
Verses 1-8:
"Book," sepher, denotes a register or complete writing, as of a record. This register lists ten generations, from Adam to Noah. The existence of this written record confirms the high state of civilization from the very beginning of human history. Men were not ignorant, near-savage beings. They were highly skilled in arts and sciences and trades and crafts.
The listing of genealogies begins with Adam. He was humanity’s only special act of Divine creation, 1Co 15:45. All others came from him, by process of natural generation. Verses 1 and 2 re-affirm the original creation, Ge 1:26-28.
Adam and Eve had other sons and daughters beside the three mentioned in the sacred text. There is no way to know how many children they had. The ravages of sin had not become so pronounced during their lifetime. This means that they maintained youthful vigor and health far longer than people of later times. The earth and its atmosphere were not poisoned by the noxious chemicals and pollutants that reek havoc with human health. It is quite possible that Adam and Eve had literally scores or perhaps hundreds of children.
The life-span of pre-flood men was very long. Adam lived to be 930 years of age. Some interpreters suggest that these ".’years" were shorter periods of time than the ordinary "years" of 365 days, thus implying that Adam was in reality only about one hundred, or at the most two hundred years old, at the time of his death. If this same formula is applied to Seth, it would mean that Enos was born to him even before Seth’s birth! Also, it would place the birth of later patriarchs in this genealogical table at impossible times.
