I have placed my rainbow in the clouds. It is the sign of my covenant with you and with all the earth. When I send clouds over the earth, the rainbow will appear in the clouds, and I will remember my covenant with you and with all living creatures. Never again will the floodwaters destroy all life.
When I see the rainbow in the clouds, I will remember the eternal covenant between God and every living creature on earth.” Then God said to Noah, “Yes, this rainbow is the sign of the covenant I am confirming with all the creatures on earth.”
Genesis 9:13-17 NLT
