Genesis 7:1-6

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

2Of all clean beasts thou shalt take to thee by sevens, a male and its female; but of the beasts that are not clean two, a male and its female.

3Also of the fowl of the heavens by sevens, male and female; to keep seed alive on the face of all the earth.

4For in yet seven days I will cause it to rain on the earth forty days and forty nights; and every living being which I have made will I destroy from the ground.

5And Noah did according to all that Jehovah had commanded him.

6And Noah was six hundred years old when the flood of waters was on the earth.
