When man began to multiply on the face of the land and daughters
were born to them, the sons of God saw that the daughters of man
were attractive. And they took as their wives any they chose. Then
the LORD said, “My Spirit shall not abide in man forever, for he is
flesh: his days shall be 120 years.” The Nephilim were on the earth
in those days, and also afterward, when the sons of God came in to
the daughters of man and they bore children to them. These were the
mighty men who were of old, the men of renown.

 The LORD saw that the wickedness of man was great in the earth,
and that every intention of the thoughts of his heart was only evil
continually. And the LORD regretted that he had made man on the
earth, and it grieved him to his heart. So the LORD said, “I will
blot out man whom I have created from the face of the land, man and
animals and creeping things and birds of the heavens, for I am
sorry that I have made them.” But Noah found favor in the eyes of
the LORD.

 These are the generations of Noah. Noah was a righteous man,
blameless in his generation. Noah walked with God. And Noah had
three sons, Shem, Ham, and Japheth.

 Now the earth was corrupt in God's sight, and the earth was
filled with violence. And God saw the earth, and behold, it was
corrupt, for all flesh had corrupted their way on the earth. And
God said to Noah, “I have determined to make an end of all flesh,
for the earth is filled with violence through them. Behold, I will
destroy them with the earth. Make yourself an ark of gopher wood.
Make rooms in the ark, and cover it inside and out with pitch. This
is how you are to make it: the length of the ark 300 cubits, its
breadth 50 cubits, and its height 30 cubits. Make a roof for the
ark, and finish it to a cubit above, and set the door of the ark in
its side. Make it with lower, second, and third decks. For behold,
I will bring a flood of waters upon the earth to destroy all flesh
in which is the breath of life under heaven. Everything that is on
the earth shall die. But I will establish my covenant with you, and
you shall come into the ark, you, your sons, your wife, and your
sons' wives with you. And of every living thing of all flesh, you
shall bring two of every sort into the ark to keep them alive with
you. They shall be male and female. Of the birds according to their
kinds, and of the animals according to their kinds, of every
creeping thing of the ground, according to its kind, two of every
sort shall come in to you to keep them alive. Also take with you
every sort of food that is eaten, and store it up. It shall serve
as food for you and for them.” Noah did this; he did all that God
commanded him.
