Genesis 7:6, 8-13

Noah was 600 years old when the flood covered the earth.

With them were all the various kinds of animals—those approved for eating and for sacrifice and those that were not—along with all the birds and the small animals that scurry along the ground. They entered the boat in pairs, male and female, just as God had commanded Noah. After seven days, the waters of the flood came and covered the earth. When Noah was 600 years old, on the seventeenth day of the second month, all the underground waters erupted from the earth, and the rain fell in mighty torrents from the sky. The rain continued to fall for forty days and forty nights. That very day Noah had gone into the boat with his wife and his sons—Shem, Ham, and Japheth—and their wives.
