What was Noah's age when he entered the Ark, according to Genesis?

According to Genesis, Noah was 600 years old when he entered the Ark. Genesis 7:6 places Noah’s age at 600 years when the Flood waters came upon the earth.

The figure belongs to the long lifespans attributed to several antediluvian figures in Genesis. The same book says Noah was 500 years old when his sons were born and later records that he lived to 950. These ages are part of the biblical genealogical and narrative framework.

Noah’s age at the Flood is sometimes confused with the age when he became the father of his sons or with his total lifespan. Genesis distinguishes those milestones: the sons are introduced when Noah is 500, the Flood begins when he is 600, and his death is recorded at 950. The question’s figure therefore refers specifically to his entry into the Ark.
