Additional guarantees.
One day, seeing a rainbow in the sky, a man heard a voice saying that the world would no longer be destroyed, and he accepted it.
But as the years passed, people began to reinterpret everything they were told in their own way... you know, like modern fashion, when a jacket looks like trousers, and the trousers look like a jacket with short, ill-fitting sleeves, worn where trousers should be.
So, looking around, for some reason, people seek additional guarantees of what was said then, but for them, it's unstable... perhaps they want to see two rainbows at once?
