'Rainbow' in the Bible

I've set my rainbow in the sky to symbolize the covenant between me and the earth.

Whenever I bring clouds over the earth and the rainbow becomes visible in the clouds,

When the rainbow is in the clouds, I will observe it and remember the everlasting covenant between God and all living beings on the earth."

And God said to Noah, “This [rainbow] is the sign of the covenant (solemn pledge, binding agreement) which I have established between Me and all living things on the earth.”
