Genesis 7:8

⁶  And Noah was six hundred years old when the flood of waters was upon the earth.

⁷  And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.

⁸  Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,

⁹  There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.

¹⁰  And it came to pass after seven days, that the waters of the flood were upon the earth.
