So what about the salt that is “good for nothing"?

Last post (probably!) on salt.
What about that salt that has lost its savor?--that is “good for nothing and can only be thrown out to be trampled under people’s feet”(Matthew 5:13). Jesus wasn’t just speaking figuratively: in biblical times they did with low-grade salt something like what we do today: they put it on the marble courtyards of the Temple after rain to make them less slippery. Indeed, trampled underfoot.
