Hezekiah's repair of the Millo is mentioned within a list of repairs to military fortifications, and several scholars generally believe that it was something connected to military activity, such as a tower, citadel, or simply a significant part of a wall. However, taking into account that the potentially cognate term mulu, from Assyrian, refers to earthworks, it is considered more likely that it was an embankment which flattened the slope between Ophel and the Temple Mount.
