It took place in a neighbor's large succah.
Considering that even today, after seventy 70 years of the State of Israel, which bli eyin haraa, seems stronger and more stable and successful than ever, many Jews still have trouble accepting this reality, talk of the measurements of the Third Temple may seem a bit "premature." But as I listened I thought of how just barely a hundred and fifty years ago, the vast majority of Jews couldn't fathom the idea that there would be a Jewish State. They thought that Theodor Herzl and other early Zionists were totally daft.
I kept thinking of this famous quotation from Theodor Herzl as I listened to a very detailed explanation of dimensions of the yet unbuilt Holy Temple. Gd willing we won't need to wait much longer to liberate the Temple Mount and build the Third Temple.
If you will it, it is no dream
