Genesis 7:7

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.

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

7And Noah went in, and his sons, and his wife, and his sons’ wives with him, into the ark, because of the waters of the flood.

8Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,

9There went in two and two unto Noah into the ark, the male and the female, as God had commanded Noah.

10And it came to pass after seven days, that the waters of the flood were upon the earth.

11In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened.
