Genesis 6:17LXX

15And this which thou shalt make it : The length of the ark three hundred cubits, the breadth of it fifty cubits, and the height of it thirty cubits.

16A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; lower, second, and third shalt thou make it.

17And, behold, I, even I, do bring a flood of waters upon the earth, to destroy all flesh, wherein the breath of life, from under heaven; every thing that in the earth shall die.

18But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons' wives with thee.

19And of every living thing of all flesh, two of every shalt thou bring into the ark, to keep alive with thee; they shall be male and female.
