"The 'foot' structures that we found in the Jordan valley are the first sites that the People of Israel built upon entering Canaan and they testify to the biblical concept of ownership of the land with the foot," said archaeologist Prof. Adam Zertal of the University of Haifa, who headed the excavating team that exposed five compounds in the shape of an enormous "foot", that it were likely to have been used at that time to mark ownership of territory.Worth reading the entire article here.

On the eve of the Passover holiday, researchers from the University of Haifa reveal an exceptional and exciting archaeological discovery that dates back to the time of the People of Israel's settlement in the country: For the first time, enclosed sites identified with the biblical sites termed in Hebrew "gilgal", which were used for assemblies, preparation for battle, and rituals, have been revealed in the Jordan valley. The researchers, headed by Prof. Adam Zertal, exposed five such structures, each in the shape of an enormous "foot", which they suppose functioned during that period to mark ownership on the territory. "I am an archaeologist and only deal with the scientific findings, so I do not go into the additional meanings of the discovery, if there are any," Prof. Zertal said.
