Why Did Israel Set Up Memorial Stones?
Biblical peoples were very fond of symbolic acts to commemorate great events. In order to memorialize God’s blessing in parting the waters of the Jordan River, Joshua commanded that twelve stones be taken from the riverbed and placed where all the people could see them: “These stones shall be for a memorial unto the children of Israel for ever” ( v. 7 ). In later years, when their children would ask the meaning of the stones, Israel could rehearse the story of God’s miracle; thus, the stones would serve as a visible reminder of God’s power.
