By looking at 1 Chronicles 4:23. The fact the royal potteries mentioned in the text are located just on the edges of the Elah valley (as the Tel Socoh website states regarding the petrographic origin of the lmlk jars!) makes it ever more likely Gederoth (Khirbet Judraya, 31°41’19″N, 34°59’46″E) and Netaim (Khirbet Nuweitih, 31°40’43″N, 34°56’26″E) were the true lmlk (or at least rosette) potteries (although I still suspect the actual lmlk pottery is at Achzib/Tell el-Beidah for the reasons mentioned below). The locating of these royal potteries in the Elah Valley also explains why some Persian tax jars were made in the Shephelah-the royal potters may have re-settled Gederah and Netaim during the First Return. However, placing the lmlk potteries in the Elah Valley poses problems for my locations of the lmlk impressions’ MMST in the Gedor/Halhul district (as the first MMST jars were made near Jerusalem) and the lmlk Socoh in the southern Hill Country. We must remember there are good reasons to thinking that the lmlk Socoh was the southern one. There is only one way to solve this conundrum-survey and/or excavate Tell el-Beida, Khirbet Nuweitih, and Khirbet Judraya!!!
