In July of 2010, a clay fragment was discovered in Jerusalem that dated back to the 14th Century BC. It would appear to be part of a governmental archive and serves as evidence that Jerusalem was the seat of government as far back as the 1400 years before Christ. This confirms the Biblical view that Jerusalem was prominent going well back into history.

Additionally, Israeli archeologists have confirmed the existence of large fortifications/walls around Jerusalem dating to the 10th Century BC (i.e., the time of Solomon). This shows that Jerusalem was a significant governmental center at the time and confirms Biblical claims that the city was the seat of government for a significant power state/military power at the time.

Finally, the existence of the âBroad Wallâ shows that Jerusalem was still significant at the time of Hezekiah and then again at the time of Nehemiah.
