Genesis 8:20-22
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.”
Genesis 9:8-17
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.”
