Genesis 7:16

12And the rain was upon the earth forty days and forty nights.

13In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;

14They, and every beast after his kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort.

15And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life.

16And they that went in, went in male and female of all flesh, as God had commanded him: and the Lord shut him in.

17And the flood was forty days upon the earth; and the waters increased, and bare up the ark, and it was lift up above the earth.

18And the waters prevailed, and were increased greatly upon the earth; and the ark went upon the face of the waters.

19And the waters prevailed exceedingly upon the earth; and all the high hills, that were under the whole heaven, were covered.

20Fifteen cubits upward did the waters prevail; and the mountains were covered.
