This story is pretty neat. It's a tablet, which claims to be from the times of King Y'ho-uhsh (Judaen King).
As the story points out, it's ironic. As the Arabs are denying that a temple ever stood there, they are trying to remove any proof of them. Denying the second temple is nearly impossible, as the evidence is so great. However, the First Temple has little evidence (outside of the T'nach), so they have a better chance at denying that. And it was while destroying the temple mount that this tablet came to light.
Interestingly enough, it's written in Phoenician. I am still wondering at what point in history did the largest amount of people speak Hebrew. I assume when the Jews left Egypt. But I even wonder if then it was a primary laguage. Adam, Eve, and their offspring all spoke Hebrew, but the poplation as decimated during the Deluge. Then Hebrew rose with Noah, but slightly afterwards everyone split off "to their languages". By the time the Tower of Babel came along there were seventy different laguages (besides Hebrew). Everyone just also knew Hebrew (similar to English, or French, today). After the Tower of Babel most did not know Hebrew.
