There was one of the Jews from the south who could jump a mile. He was so swift that he alone could kill all of the Roman army. The Caesar put his crown on the ground and prayed, “Master of the entire world, do not let me be shamed through a single man.” The southerner, however, said differently: “God, you have forsaken us,” implying that he will defeat the Romans alone anyway. That was the cause of his downfall, since when he went into the toilet, and snake bit him and he died. Caesar retreated, in gratitude that God answered his prayer. The Jews misunderstood and celebrated their victory. On seeing that, Caesar came back and destroyed Har HaMelech.
The Talmud described another place where righteous Jews were killed and asks, why? It answers – because they did not mourn the destruction of Jerusalem – while one should be in joy when Jerusalem is being rebuild and mourn when it is destroyed.
