The LORD saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually.
 And the LORD was sorry 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 ground, man and beast and creeping things and birds of the air, for I am sorry that I have made them."
 But Noah found favor in the eyes of the LORD.
 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 three hundred cubits, its breadth fifty cubits, and its height thirty 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 from 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; and it shall serve as food for you and for them."
 Noah did this; he did all that God commanded him.
The flood continued forty days upon the earth; and the waters increased, and bore up the ark, and it rose high above the earth.
 He blotted out every living thing that was upon the face of the ground, man and animals and creeping things and birds of the air; they were blotted out from the earth. Only Noah was left, and those that were with him in the ark.
 And the waters prevailed upon the earth a hundred and fifty days.
But God remembered Noah and all the beasts and all the cattle that were with him in the ark. And God made a wind blow over the earth, and the waters subsided.
At the end of forty days Noah opened the window of the ark which he had made,
 and sent forth a raven; and it went to and fro until the waters were dried up from the earth.
 Then he sent forth a dove from him, to see if the waters had subsided from the face of the ground;
 but the dove found no place to set her foot, and she returned to him to the ark, for the waters were still on the face of the whole earth. So he put forth his hand and took her and brought her into the ark with him.
 He waited another seven days, and again he sent forth the dove out of the ark;
 and the dove came back to him in the evening, and lo, in her mouth a freshly plucked olive leaf; so Noah knew that the waters had subsided from the earth.
 Then he waited another seven days, and sent forth the dove; and she did not return to him any more.
In the six hundred and first year, in the first month, the first day of the month, the waters were dried from off the earth; and Noah removed the covering of the ark, and looked, and behold, the face of the ground was dry.
 In the second month, on the twenty-seventh day of the month, the earth was dry.
 Then God said to Noah,
 "Go forth from the ark, you and your wife, and your sons and your sons' wives with you.
 Bring forth with you every living thing that is with you of all flesh -- birds and animals and every creeping thing that creeps on the earth -- that they may breed abundantly on the earth, and be fruitful and multiply upon the earth."
 So Noah went forth, and his sons and his wife and his sons' wives with him.
 And every beast, every creeping thing, and every bird, everything that moves upon the earth, went forth by families out of the ark.
Then Noah built an altar to the LORD, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar.
 And when the LORD smelled the pleasing odor, the LORD said in his heart, "I will never again curse the ground because of man, for the imagination of man's heart is evil from his youth; neither will I ever again destroy every living creature as I have done.
 While the earth remains, seedtime and harvest, cold and heat, summer and winter, day and night, shall not cease."
