In the framework of the regional project in the Judean Shephelah, which started in 2007, four sites were investigated: Khirbet Qeiyafa, hirbet el-Ra‘i, Socoh, and Lachish. The data for the 10th century is presented here together with the relevant biblical traditions. The data is analyzed according to an urban geography model and the gradual development and territorial expansion of the Kingdom of Judah is suggested.
