After my mum died and while we were planning for her funeral, during one dramatic day after we had left the funeral home, my dad and I saw a giant double rainbow in the sky. I understand that single rainbows are a sign of God's covenant with us. But, can you please tell me what a double rainbow is a sign of? Is there something in the Torah or in any other Jewish writings that provides an understanding of the meaning of a double rainbow?
