The number 950 is linked to Noah's total lifespan according to Genesis 9:29.
According to the Bible, Noah lived 950 years before he died (Gen 9:29), making this number a symbol of the extraordinarily long lives of the pre-flood patriarchs. Noah lived 600 years before the flood and 350 years after it, and his total lifespan marks the transition from the old world to the new. In Jewish tradition, Noah's advanced age reflects God's grace and the original vitality that humanity possessed in early times. After Noah, life expectancy gradually decreased through subsequent generations, which is traditionally understood as a consequence of sin's effect on the world. Noah was 600 years old when the flood came (Gen 7:6) and lived 350 years after the flood (Gen 9:28). The division of his life into two eras – before and after the flood – has been seen as a picture of the old and the new creation. In rabbinic tradition, the decline in lifespan from Noah (950 years) through Shem, Arpachshad, and further down the genealogies is discussed as an expression that the world gradually moved away from its original perfection. Some rabbis link this to the concept of 'yeridas ha-doros' (the descent of the generations). Noah's age of 950 years makes him the third longest-lived person mentioned in the Bible, after Methuselah (969 years) and Jared (962 years).*
