Hendel on the rainbow

RON HENDEL: The Rainbow in Ancient Context. What does it mean for the rainbow to be a sign of God’s covenant with life on earth, and how does this compare with other concepts of the rainbow in the ancient world? (TheTorah.com). Excerpt:

The rainbow is a sign of many things. It is a visual sign of the covenant between God and all living creatures, a glittering and mysterious bridge between sky and earth. It is a sign of peace, reconciliation, and the eternity of moral law. We remember these things – even if not altogether consciously – when the rain lets up and the sun shines through the clouds, creating the momentary wonder of the rainbow. Although we know that the rainbow is a natural effect of light after the rain, it is also a sign of biblical memory in our lives and perceptions.

A good discussion of the ancient context of the rainbow in the biblical Flood story, but I was hoping that Ezekiel 1:28 would be brought in as well.
