Genesis 7:2-4

Revised Standard Version

² Take with you seven pairs of all clean animals, the male and his mate; and a pair of the animals that are not clean, the male and his mate; ³ and seven pairs of the birds of the air also, male and female, to keep their kind alive upon the face of all the earth. ⁴ For in seven days I will send rain upon the earth forty days and forty nights; and every living thing that I have made I will blot out from the face of the ground.”
