The last of the Elders (z'keinim) who were contemporaries of Joshua and outlived him, passed away in the year 2533 after creation. They were part of the chain of Torah transmission as listed at the beginning of Ethics of the Fathers: "Moses received the Torah from Sinai and gave it over to Joshua. Joshua gave it over to the Elders, the Elders to the Prophets..."
In ancient times, this day was marked as a fast day.
[Some are of the opinion that this occurred on the 5th of Shevat].
There will come a time, very soon, when we will be shown miracles so great, they will make the Ten Plagues and the splitting of the Red Sea appear as ordinary as nature itself.
So great, no mind can begin to fathom them;
so powerful, they will transform the very fabric of our world, elevating it in a way that the wonders of the Exodus could not achieve.
For then, our eyes will be opened and granted the power to see the greatest of miracles.
And what are those miracles?
Those that occur to us now, beneath our very noses, every day.
