'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."

The appearance of the radiant light resembled that of a rainbow shining in a cloud on a rainy day. This was what the appearance of the form of the glory of the LORD resembled. When I saw all of this, I fell flat on my face. Then I heard a voice speaking.
