An article of mine (see here a link to a proofs of the article, as the final one is under copyright) has just appeared that deals with archaeological evidence of the Arameans in the Iron Age II Southern Levant, covering various sites – including Tell es-Safi/Gath.
The full title of the article is:
Maeir, A. M. 2016. The Aramaean Involvement in the Southern Levant: Case Studies for Identifying the Archaeological Evidence. Pp. 79–87 in In Search of Aram and Israel: Politics, Culture and Identity, eds. O. Sergi, M. Oeming and I. J. de-Hulster. Orientalische Religionen in der Antike. Tübingen: Mohr-Siebeck.
The paper was published as part of a very nice volume, edited by Omer Sergi et al., in which a very nice collection of papers relating to the relations between Israel and Aram in biblical times were collected, based for the most part on a conference on the topic that was held in Heidelberg some two years ago.
