Genesis 7:2-4

New Revised Standard Version, Anglicised Catholic Edition

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