When human beings began to increase in number on the earth and daughters were born to them, the sons of God saw that the daughters of humans were beautiful, and they married any of them they chose. Then the Lord said, ‘My Spirit will not remain with humans for ever, for they are mortal; their days will be a hundred and twenty years.’

The giants were on the earth in those days – and also afterwards – when the sons of God went to the daughters of humans and had children by them. They were the heroes of old, men of renown.

The Lord saw how great the wickedness of the human race had become on the earth, and that every inclination of the thoughts of the human heart was only evil all the time. The Lord regretted that he had made human beings on the earth, and his heart was deeply troubled. So the Lord said, ‘I will wipe from the face of the earth the human race I have created – and with them the animals, the birds and the creatures that move along the ground – for I regret that I have made them.’  But Noah found favour in the eyes of the Lord.

Now the earth was corrupt in God’s sight and was full of violence. ¹God saw how corrupt the earth had become, for all the people on earth had corrupted their ways. So God said to Noah, ‘I am going to put an end to all people, for the earth is filled with violence because of them. I am surely going to destroy both them and the earth. So make yourself an ark of cypress wood; make rooms in it and coat it with pitch inside and out….

The Lord then said to Noah, ‘Go into the ark, you and your whole family, because I have found you righteous in this generation…

In the six hundredth year of Noah’s life, on the seventeenth day of the second month – on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened. And rain fell on the earth for forty days and forty nights…

For forty days the flood kept coming on the earth, and as the waters increased, they lifted the ark high above the earth…

Every living thing that moved on land perished – birds, livestock, wild animals, all the creatures that swarm over the earth, and all mankind. Everything on dry land that had the breath of life in its nostrils died. Every living thing on the face of the earth was wiped out; people and animals and the creatures that move along the ground and the birds were wiped from the earth. Only Noah was left, and those with him in the ark.

The waters flooded the earth for a hundred and fifty days…

But God remembered Noah and all the wild animals and the livestock that were with him in the ark, and he sent a wind over the earth, and the waters receded. Now the springs of the deep and the floodgates of the heavens had been closed, and the rain had stopped falling from the sky.The water receded steadily from the earth. At the end of the hundred and fifty days the water had gone down,..

After forty days Noah opened a window he had made in the ark and sent out a raven, and it kept flying back and forth until the water had dried up from the earth. Then he sent out a dove to see if the water had receded from the surface of the ground. But the dove could find nowhere to perch because there was water over all the surface of the earth; so it returned to Noah in the ark. He reached out his hand and took the dove and brought it back to himself in the ark. He waited seven more days and again sent out the dove from the ark. When the dove returned to him in the evening, there in its beak was a freshly plucked olive leaf! Then Noah knew that the water had receded from the earth. He waited seven more days and sent the dove out again, but this time it did not return to him.

Then God said to Noah, ‘Come out of the ark, you and your wife and your sons and their wives. Bring out every kind of living creature that is with you – the birds, the animals, and all the creatures that move along the ground – so they can multiply on the earth and be fruitful and increase in number on it.’

So Noah came out, together with his sons and his wife and his sons’ wives. All the animals and all the creatures that move along the ground and all the birds – everything that moves on land – came out of the ark, one kind after another.

Then Noah built an altar to the Lord and, taking some of all the clean animals and clean birds, he sacrificed burnt offerings on it. The Lord smelled the pleasing aroma and said in his heart: ‘Never again will I curse the ground because of humans, even though every inclination of the human heart is evil from childhood. And never again will I destroy all living creatures, as I have done.

‘As long as the earth endures,
seedtime and harvest,
cold and heat,
summer and winter,
day and night
will never cease.’…

Then God said to Noah and to his sons with him: ‘I now establish my covenant with you and with your descendants after you and with every living creature that was with you – the birds, the livestock and all the wild animals, all those that came out of the ark with you – every living creature on earth. I establish my covenant with you: never again will all life be destroyed by the waters of a flood; never again will there be a flood to destroy the earth.’

And God said, ‘This is the sign of the covenant I am making between me and you and every living creature with you, a covenant for all generations to come: I have set my rainbow in the clouds, and it will be the sign of the covenant between me and the earth. Whenever I bring clouds over the earth and the rainbow appears in the clouds, I will remember my covenant between me and you and all living creatures of every kind. Never again will the waters become a flood to destroy all life. Whenever the rainbow appears in the clouds, I will see it and remember the everlasting covenant between God and all living creatures of every kind on the earth.’

So God said to Noah, ‘This is the sign of the covenant I have established between me and all life on the earth.’
