The Genesis Genealogies


“In a day when so many modern theologians cast doubt on the historicity of Adam, for example, it is refreshing to see a firm affirmation of historicity.”

~ Dr. Frank A. James III, President of Biblical Theological Seminary


Adam, the very first figure of the Bible, lived 930 years. He lived contemporaneously with his 7th generation descendant, Enoch, for 308 years, and Enoch was transfigured without seeing death 57 years after Adam’s death (Gen 5:21‐24). Adam lived contemporaneously with his 9th generation descendant, Lamech, for 56 years, passing on his faith. Lamech’s son, Noah, eventually became the central figure of the judgment by flood, revealing that Adam’s penitent faith had reached all the way to Noah (Gen 5:28‐29). And Noah who lived for 350 years after the flood (Gen 9:28), lived contemporaneously with his 11th generation descendant, Abraham, for 58 years. This allowed faith to be transmitted to Abraham who emerged as the new starting point of redemptive history.


Why remember the “days of old”?

Immediately before the Israelites entered into Canaan, Moses reminded them in his farewell sermon, “Remember the days of old, consider the years of all generations!” The “days of old” and “years of all generations” are not merely old fairy tales or legends. They are a recording of the providence of God, who poured out His fervent love by intervening into the history of mankind since the fall of Adam. It is a story of the fathers of faith who unshakably preserved the path of godliness according to God’s providence. As the Israelites had to remember the days of old in the wilderness when they were preparing to enter into Canaan, we Christians must also remember the days of old as we prepare to enter into the kingdom of heaven.

Rediscovery of the Genealogies

The genealogies in the book of Genesis that seemed so tedious with repetitions of names and births were actually the treasury of what we need to remember about the “days of old” and the “years of all generations.” They clearly portray God’s administration for the redemption of mankind and the entire universe. The genealogies in Genesis are only a few verses. Yet, they contain the redemptive providence over a long period of about 2,300 years. Thus, each verse and name in these genealogies is saturated with historical and redemptive significances. This book helps the readers rediscover the spiritual meaning contained within each of the 20 generations from Adam to Abraham.

The History of Redemption is the History of Separation

The book of Genesis records the genealogies of all generations, including those who have strayed away from the godly lineage, such as Cain, Ham, Ishmael, and Esau. They are examples that reflect our own sinfulness and unfaithfulness. This division between the godly lineage and the ungodly lineage continues to run together with the history of redemption. The people of God had to learn to separate themselves from the path of sin and live a consecrated life. One great example of such a life is the life of Abraham, who is probably the most prominent character in this book.


First Generation: Adam man, mankind, human

The name Adam comes from the Assyrian root adamu, meaning “to make” or “to create.” Man can never be the creator; he is only the creation and the creature. Adam was formed from the dust (Gen 2:7; 3:19, 23). The term dust is in Hebrew, meaning “dust” or “ashes,” not “mud” or “dirt.” Without the breath of God, the essence of man is only dust (Gen 18:27; Job 4:19; 33:6; Ps 103:14; Eccl 3:20; Isa 64:8; 1 Cor 15:47).

Adam lived until Lamech, the ninth generation, was 56 years old.
*Organized and presented for the first time in history*:

After the fall, Adam and Eve probably testified about their blessed lives before the fall, their fellowship with God, and the conditions in Eden. All the generations from Seth (second generation) to Lamech (ninth generation) probably received a full account from Adam about the eternal world before the fall, their spiritual experiences, Satan’s deception, the consequences of disobedience, and the promise of salvation.

Adam received the assured gospel regarding the woman’s seed (Gen 3:15) and no doubt preached this gospel to his descendants with tireless diligence because it was the only ray of hope for him and for all mankind. More than anyone else, Adam believed that the woman’s seed would come according to the promise that he received. This is evident in the name he gave to his wife after they had received the promise in Genesis 3:15: Eve (“life” [Gen 3:20]).
Through this name, Adam declared that Eve would become the mother of all the living. This was the first confession of faith in the promise of the seed and the expression of hope of that day when life conquers death. His conviction most likely strengthened each time he called out her name.

The garments of skin with which God had clothed Adam and Eve before banishing them from Eden (Gen 3:21) were the assurance of His covenant in Genesis 3:15, which for Adam was more precious than life itself. The garments made of skin imply that sacrifice is the basic principle of salvation. It also reveals how the redemption of mankind would be accomplished. This is a foreshadowing of Jesus Christ’s sacrifice on the cross, for the sacrifice of life is required to make garments of skin. Throughout his life, Adam cherished the garments of skin because they
were his confirmation of the covenant. He firmly believed that the day would come when the promised seed
would bruise the head of the serpent. This presumably is the faith that he taught and passed down to his

Did Noah really take 120 years to build the ark?

God commanded Noah to build the ark after his three sons had been born (Gen 6:10~). 

Genesis 5:32 testifies that Noah had three sons after he turned 500, Noah was five hundred years old, and Noah became the father of Shem, Ham, and Japheth.”

Genesis 11:10 states, “These are the records of the generations of Shem. Shem was one hundred years old and became the father of Arpachshad two years after the flood.”

Genesis 7:6 tells us the flood took place when Noah was 600 years old. Hence Shem turned 100 in the year Noah turned 602. Therefore, Shem was born when Noah was 502 years old which was 98 years before the flood. Just knowing Shem’s year of birth shows us that the duration of building the ark was less than 100 years.


The point in time when God revealed His plans about the flood to Noah (Gen 6:13) and when He gave the command to build the ark along with the precise plans for the ark are very important. Genesis 6:10 tells us that God commanded Noah to build the ark after he had already given birth to his three sons, Shem, Ham and Japheth.

Since Shem was born when Noah was 502 years old, it would’ve taken Noah at least 2 more years to give birth to both Ham and Japheth (since they were’t twins) and 4 or more years if they were
birthed 2 or more years apart.

Therefore, since the flood took place when Noah was 600 years old, the time it took to build the ark must’ve been fewer than 96 years.


When God commanded Noah to build the ark in Genesis 6:18, He said, “but I will establish My covenant with you; and you shall enter the ark ‐ you and your sons and your
wife, and your sons’ wives with you.”

In other words, when Noah received the command to build the ark. his sons, who had been born to him after his 500th year, had already grown and gotten married. For his three sons to have been married, they must’ve been at least 15 years old.

Considering such factors, Noah and his 7 family members (Noah’s wife, three sons, and three daughters‐in‐law) could not have built the ark for more than 70 to 80 years.


The flood starts on the 17th day of the second month of Noah’s 600th year (Gen 7:11). Noah and his family receive the revelation about the flood judgment along with the command to enter the ark 7 days before the flood (Gen 7:1‐4). If the ark had not been finished according to the plans that God had given, then it would not have survived the flood.

Therefore, the ark must’ve been completed before the 10th day of the second month of Noah’s 600th year.

This book is a sweeping vista of God’s plan of redemption from Genesis down through the ages to its final expression in the person and work of Jesus Christ. Dr. Park’s book is a journey worth taking. I heartily recommend this insightful work of Dr. Park for seminaries and colleges. I can assure readers that this book will not disappoint.

President of the Research Institute of Reformed Theology

Rev. Park uses the covenantal links to dynamically unfold the enormous biblical discourse, which no one can come close to endeavoring, from the perspective of God’s redemptive plan. He logically and perfectly depicts this theme as the central theme of Christian theology as well as the theme of his own faith and theological belief. This surely is the result of his lifelong devotion to prayer and his study of the Word with gratitude for the Lord’s grace.

After reading this book, I was not only able to feel the very message that the Bible delivers to us through historical facts, but also able to obtain an understanding of things that were not possible through other books. Furthermore, through the insights given by this book, I felt my heart overflowing with joy and vitality from studying the Bible, the Word of God. As a result, faith will not remain as stagnant knowledge, but will become apparent in life and action. The life of faith will not only remain as words, but applied through works in everyday life.
