Genesis 7:3 KJV

1And the LORD said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.

2Of 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.

3Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.

4For 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.

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