Siege Of Jerusalem

The Biblical account of Sennacherib's siege of Jerusalem begins with the destruction of the Northern Kingdom of Israel and its capital Samaria. This is how the ten northern tribes came to be known as the Ten Lost Tribes, because as recorded in II Kings 17, they were carried off and settled with other peoples as was the Assyrian policy. II Kings 18-19 (and parallel passage II Chronicles 32:1-23) details Sennacherib's attack on Judah and capital Jerusalem. Hezekiah had rebelled against the Assyrians, so they had captured all of the towns in Judah.

Defeat Of Sennacherib's Army

Disaster in Egypt according to Herodotus

The Greek historian Herodotus,  who wrote his Histories ca. 450 BC, speaks of a divinely-appointed disaster destroying an army of Sennacherib (2:141):

"...when Sanacharib, king of the Arabians and Assyrians, marched his vast army into Egypt, the warriors one and all refused to come to his (i.e., the Pharaoh Sethos aid.) On this the monarch, greatly distressed, entered into the inner sanctuary, and, before the image of the god, bewailed the fate which impended over him. As he wept he fell asleep, and dreamed that the god came and stood at his side, bidding him be of good cheer, and go boldly forth to meet the Arabian host, which would do him no hurt, as he himself would send those who should help him. Sethos, then, relying on the dream, collected such of the Egyptians as were willing to follow him, who were none of them warriors, but traders, artisans, and market people; and with these marched to Pelusium, which commands the entrance into Egypt, and there pitched his camp. As the two armies lay here opposite one another, there came in the night, a multitude of field-mice, which devoured all the quivers and bowstrings of the enemy, and ate the thongs by which they managed their shields. Next morning they commenced their fight, and great multitudes fell, as they had no arms with which to defend themselves. There stands to this day in the temple of title "Vulcan", a stone statue of Sethos, with a mouse in his hand, and an inscription to this effect - "Look on me, and learn to reverence the gods."

The Cyrus Cylinder

The Cyrus Cylinder, discovered in 1879 and now in the British Museum, is one of the most famous cuneiform texts, because it was once believed that it confirmed what the Bible says (Isaiah 44.23-45.8; Ezra 1.1-6, 6.1-5; 2 Chronicles 36.22-23): that in 539 BCE, the Persian conqueror Cyrus the Great had allowed the Jews to return from their Babylonian Exile.

The Nabonidus Cylinder

This clay cuneiform cylinder was discovered in the Temple of Shamash at Sippar. It records the pious reconstruction by Nabonidus (reigned 555-539 BC) of the temples of the moon-god Sin in Harran and of the sun-god Shamash and goddess Anunitum at Sippar. He tells us that during the work at Sippar, inscriptions of older kings Naram-Sin (2254-2218 BC) and Shagaraki-shuriash (1245-1233 BC) were discovered, and Nabonidus offers dates that considerably exaggerate their age.

The Black Obelisk

The Black Obelisk is a significant artifact from his reign. It is a black limestones,  bas-relief  sculpture from Nimrud (ancient Kalhu), in northern Iraq.  It is the most complete Assyrian obelisk yet discovered, and is historically significant because it displays the earliest ancient depiction of an Israelite. On the top and the bottom of the reliefs there is a long cuneiform inscription recording the annals of Shalmaneser III. It lists the military campaigns which the king and his commander-in-chief headed every year, until the thirty-first year of reign. Some features might suggest that the work had been commissioned by the commander-in-chief, Dayyan-Assur.
  

Hezekiah's Tunnel

A tunnel was constructed from the spring at Gihon - what is now called the Virgin's Fountain - under the city walls and through the rock to the southern end of the city of Jerusalem, to the pool of Siloam. This would be a difficult feat in these days of sophisticated surveying and measuring equipment. It was even more remarkable for the times of Hezekiah, because the impending invasion meant there was very little time and gangs of workmen had to start from either end. When the tunnel was complete, the spring outside the city was blocked up and the water flowed into the city.

The second book of Chronicles records:

"And when Hezekiah saw that Sennacherib was come, and that he was purposed to fight against Jerusalem, he took counsel with his princes and his mighty men to stop the waters of the fountains which were without the city: and they did help him. So there was gathered much people together, who stopped all the fountains and the brook that ran through the midst of the land, saying, Why should the kings of Assyria come, and find much water?" (2 Chronicles 32:2-4)
"And the rest of the acts of Hezekiah, and all his might, and how he made a pool, and a conduit, and brought water into the city, are they not written in the book of the chronicles of the kings of Judah?" (2 Kings 20:20)

Sack Of Jerusalem

 The fall of Jerusalem in 586 BC was accompanied by terrible destruction and much loss of life. "And all the vessels of the house of God, great and small, and the treasures of the house of the Lord, and the treasures of the king and of his friends, all these he (Nebuchadnezzar) brought to Babylon. And they burned the house of God, and broke down the wall of Jerusalem, and burned all its palaces with fire, and destroyed all its precious vessels," (II Chronicles 36:18,19). A parallel account in II Kings 25 describes the seized vessels of the house of the Lord as including pots, snuffers, dishes for incense, firepans, bowls, etc.

It is possible that some of the wealth of the temple and some of the treasures of the king's house was hidden under the temple mount though this is mostly speculation. If anything was hidden it would most likely have been the Ark of the Covenant which was of great sacred importance.
