Rob Bradshaw has posted an article by Eugene D. Stockton, on “The Fortress Temple of Shechem and Joshua’s Covenant.” The article was published in the Australian Journal of Biblical Archaeology 1.1 (1968): 24-28.
The following is an excerpt from the article:
Two covenant ceremonies conducted by Joshua at Shechem are described in Jos. 8, 30-35 (cf. Deut. 27) and Jos. 24, but one may be the doublet of the other. “The sanctuary of the Lord” (Jos. 24, 26) need not have been that excavated at Shechem, though it is hardly likely that the one place boasted two shrines, both connected with covenant, at the same time. The second account makes mention of a single great stone in the sanctuary which stood as “a witness against us, for it has heard all the words of the Lord which He spoke to us” (Jos. 24, 27). It is tempting to see in this the great slab found in the forecourt of Shechem’s temple, facing the altar and the entrance.
