Excavation works in the Jewish Quarter of the Old City revealed a significant stretch—65 metres long and varying between six and seven metres wide—of a major defensive wall of Jerusalem. The construction of this wall has been dated to the late eighth or early seventh century BCE, because is built over the top of earlier, eighth century houses. The wall may have been built during preparations for the Assyrian invasion by King Hezekiah, as described in 2 Kings 20:20 and 2 Chronicles 32:2-5. Hezekiah is rebuked for his preparations by Isaiah 22:9-11, protesting that he ought to have trusted in Yhwh to protect him but also that he broke down houses to build the wall. The wall serves as a poignant reminder of the impact that warfare and royal authority could have on the lives of individuals. This part of the wall must have been still standing after the the Babylonian sieges in 597 and 586 BCE, although other parts of it would undoubtedly have succumbed to the onslaught of the Babylonian siege engines.
