Genesis 7:1-5

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.
