Genesis 7:2-5

King James Version

² Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that are not clean by two, the male and his female.

³ Of fowls also of the air by sevens, the male and the 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 substance that I have made will I destroy from off the face of the earth.

⁵ And Noah did according unto all that the Lord commanded him.
