The Siege of Jerusalem in the year 70 AD was the decisive event of the First Jewish-Roman War. 

Esau being Rome, goes to war against Jacob (Israel) :

The Roman army, led by the future Emperor Titus, with Tiberius Julius Alexander as his second-in-command, besieged and conquered the city of Jerusalem, which had been occupied by its Jewish defenders in 66 AD.

The siege ended with the sacking of the city and the destruction of its famous Second Temple. 

The Roman legions quickly crushed the remaining Jewish resistance.

Part of the remaining Jews escaped through hidden underground tunnels, while others made a final stand in the Upper City. 

This defence halted the Roman advance as they had to construct siege towers to assail the remaining Jews.

The city was completely under Roman control by September 7 and the Romans continued to pursue those who had fled the city.

After The Romans had finished slaying people and plundering the goods that were in the city,

Titus] Caesar gave orders that they should now demolish (destroy) the entire city and Temple.

This was the exile which exiled the Jews from their own land until their return which occured in the year 1948.

The destruction of both the first and second temples is still mourned annually as the Jewish fast Tisha B’Av. 

But for all the rest of the wall [surrounding Jerusalem],

it was so thoroughly laid even with the ground by those that dug it up to the foundation, that there was left nothing to make those that came thither believe it [Jerusalem] had ever been inhabited.

The Arch of Titus, celebrating the Roman sack and the destroying of Jerusalem and the Temple, still stands in Rome.
