Scholars such as Israel Finkelstein, Lily Singer-Avitz, Ze'ev Herzog and David Ussishkin do not accept these conclusions. Finkelstein does not accept the dating of these structures to the 10th century BCE, based in part on the fact that later structures on the site penetrated deep into underlying layers, that the entire area had been excavated in the early 20th century and then backfilled, that pottery from later periods was found below earlier strata, and that consequently the finds collected by E. Mazar cannot necessarily be considered as retrieved in situ.
