Ophel and Millo are terms used in scripture to describe different parts of the City of David.
One reference can be found in the first Book of Kings (11:27), as King Solomon is described as building the construction, which was dubbed the 'Millo.': '… Solomon built up the 'Millo' and closed up the breach in the wall of the City of David his father.'
The location was built on top of a narrow, steep ridge overlooking hills and valleys that divided the land and made it difficult to move from one area to another.
'We are confident that [the moat] was used at the time of the First Temple and the Kingdom of Judah [in the ninth century BC], so it created a clear buffer between the residential city in the south and the upper city in the north,' Dr Shalev said.
According to the researchers, the moat was designed to change the City of David's topography to display Jerusalem's ruler's powers over others who entered their gates and emphasized their strength and capability to defend their walls at the time."
