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.’ ⁵ And Noah did all that the Lord had commanded him.
