See David Ussishkin, “The Date of the Judean Shrine at Arad,” Israel Exploration Journal 38 (1988), pp. 142–157. On Arad ostracon #14, referring to measures to be taken in the event of an Edomite attack, see Yohanan Aharoni, Arad Inscriptions (Jerusalem: Israel Exploration Society, 1981), pp. 46–49. Aharoni’s stratigraphy has also been questioned by Yigael Yadin, Ehud Netzer, Amihai Mazar and others.
