Genesis 7:1-6 RSV

1 Then the LORD said to Noah, "Go into the ark, you and all your household, for I have seen that you are righteous before me in this generation.
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."
5 And Noah did all that the LORD had commanded him.
6 Noah was six hundred years old when the flood of waters came upon the earth.
