Why Did People In The Bible Live So Long

Have you ever wondered why people in the Bible lived such long lives? After studying the relevant Biblical passages and delving into the available data we can uncover the reasons why people in ancient times could reach the remarkable age of 900 years, such as Methuselah (Genesis 5:27).

One of the primary theories is that the air and environment were much cleaner back then compared to today. Air and water pollution levels are much higher these days, and clean air is essential for better oxygen levels. Oxygen is an important gas, as it helps maintain our cells and repair them from possible damages. As the Scripture does not mention the presence of smoke, construction or industrial pollutants in ancient times, the air was relatively clean, providing people with good health and longer lifespans.

In addition, better diets, fresh organic food and liquid sources, such as water from rivers and wells, also contributed to longer lives. In that time, people had fewer food-processing machines and more nutritious food due to soil and climate, as well as more manual labor, leading to a healthier lifestyle. Moreover, fewer exotic animals existed in Bible times than today, meaning diets were much simpler and could have provided additional benefits to health.

Furthermore, the Bible states that God’s Presence in everyday life kept families safe, content and even healthy since they were not exposed to any kind of danger or intense psychological pressure. Experts cite this spiritual support as the key factor in their long life spans, as faith and trust in the Higher Power helps to keep stress levels low, a vital factor for a long and healthy life.

Another hypothesis is that the pre-Flood world behaved differently than today, due to several aspects, such as the distribution of land, temperature, sea levels and radiation, amongst other things. This factor could have contributed to the longer lifespan of pre-Flood people. Additionally, the post-Flood world saw the appearance of several disasters, such as the seven years of famine and the destruction of Sodom and Gomorrah, which could have caused an overall drop in quality of life.

The Social Impact of Longer Lifespans in Biblical Times

Long lifespans in Biblical times had a lasting impact in terms of inter-generational relationships, with family members and faith leaders sharing knowledge and wisdom, as well as structuring the whole community. When people lived longer, history was passed down and the activities of different generations intersected. According to leading scholars, this social aspect had a great influence in the nation-building process of the Israelites.

The impact of ancient tribes living in new territories was highly dependent on the longevity of their elders, both men and women, and the knowledge passed down from one generation to the next. This is due to the fact that, in ancient times, elders were the keepers of traditions and the key decision makers in the family, given their historical and spiritual experience. Longevity thus provided pre-historic communities the necessary connection between past and present.

The Bible often refers to people living over a hundred years, providing not only detailed genealogies but also a strong and opinionated influence. The elderly were respected by the younger tribes for their long life experience and were often considered influential sources of knowledge and authority in Ancient Israel.

The Significance of Longevity in Ancient Israel

The significance of longevity in ancient Israel is stated in the Bible and written extensively in various academic texts. According to leading scholars, a person’s life cycle falls into six 1st millennium CE stages: infancy, childhood, adulthood, sabbatical, retirement and decline. Each stage had its own set of responsibilities triggered by age and gender, helping to shape the foundations of modern day Jewish faith.

The concept of lifecycle stages was important for the formation of Ancient Israel’s moral and ethical codes, being rooted in the instruction of the Patriarchs, especially Abraham, Isaac and Jacob. The long life spans of Biblical characters suggest people also lived longer and had a great impact on their beliefs and practices. This demonstrates how longevity was important to the formation and survival of Ancient Israel’s cultural, religious and familial practices.

For instance, the Torah (Deuteronomy 25) states that, in order to keep Mosaic Law and achieve God’s blessing, Israelites should accept the inheritance of their eldest son, who has the longest life experience and the rightful spiritual knowledge and progressive views, motivated by their faith.

The Role of God in Longevity

In examining the topic of longevity in the Bible, it is important to consider the role that God plays in prolonging life. Throughout Scripture, we are confronted with numerous cases of God intervening and granting long lifespans due to people’s faith and trust in God, as well as their deeds to fulfill his will. For instance, in Genesis 6:3, God states that people shall not live for more than 120 years, and later in Exodus, we learn of Moses’ long life due to God’s promise and grace.

In Leviticus 19:32, God commands the Israelites to “honor your father and your mother” in order to live longer and avoid ill-treatment of elders. It is therefore clear that in the Bible, longevity is granted to those who take care of their elders and provide them with a meaningful life.

God frequently intervenes in the lives of his chosen people, protecting them from early death due to war, infection, famine or nature’s disasters, providing long life and giving them a chance to restore their faith in Him and the covenant.

The Link Between Longevity and Moral Stability

Longevity in the Bible is often associated with moral stability and for good reason. Referred to as Adamic or Noahic longevity, it was meant to provide men an opportunity to live holy and moral lives, as well as serve God’s people. The Bible explains that long life was a result of either moral or spiritual perfection, or of a unique connection to God’s grace, such as the case of Noah in Genesis

On the other hand, the Bible also reveals that extended lifespans could be taken away due to wicked behavior, such as with the giants, who were full of destruction and did not honor God’s commands. This change in longevity demonstrates the strong correlation between moral stability and longevity.

In addition to this, longevity was a blessing from God that served to protect his people, as well as their religion, for a longer period of time, making it easier for them to pass down to next generations their traditions, convictions and faith.


While modern science has yet to find a way to lengthen human life significantly, the Bible offers compelling evidence that explains why people in ancient times could reach the remarkable age of 900 years, such as Methuselah (Genesis 5:27). We explored the various theories such as the role of a cleaner environment, simpler diets, faith and trust in God, and the impact of pre-Flood and post-Flood worlds, amongst other aspects. Ancient Israel’s relevance of longevity was essential to shape the foundations of modern day Jewish faith and provide the connection between past and present. Additionally, morality and divine grace were also linked to longevity as God blessed those who respected him and his commandments with longer lifespans.
