Rainbow

I do set my bow in the cloud, and it shall be for a token of a covenant
between me and the earth.
And it shall come to pass, when I bring a cloud over the earth, that the
bow shall be seen in the cloud:
And I will remember my covenant, which is between me and you and
every living creature of all flesh;
and the waters shall no more become a flood to destroy all flesh.
Genesis 9:13-15
