Genesis 7:4 BBE

²  Of every clean beast you will take seven males and seven females, and of the beasts which are not clean, two, the male and his female;

³  And of the birds of the air, seven males and seven females, so that their seed may still be living on the face of the earth.

⁴  For after seven days I will send rain on the earth for forty days and forty nights, for the destruction of every living thing which I have made on the face of the earth.

⁵  And Noah did everything which the Lord said he was to do.

⁶  And Noah was six hundred years old when the waters came flowing over all the earth.
