Genesis 7:1-6 ASV

1 And Jehovah said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.
2 Of every clean beast thou shalt take to thee seven and seven, the male and his female; and of the beasts that are not clean two, the male and his female:
3 of the birds also of the heavens, seven and seven, male and female, to keep seed alive upon the face of all the earth.
4 For yet seven days, and I will cause it to rain upon the earth forty days and forty nights; and every living thing that I have made will I destroy from off the face of the ground.
5 And Noah did according unto all that Jehovah commanded him.
6 And Noah was six hundred years old when the flood of waters was upon the earth.
