The plan of Horvat Nahal Nissana (left) details the construction of the stone walls that form these courtyards and rooms, with narrow alleys in between. At right is a drawing of another settlement very similar in plan, size and overall appearance to Horvat Nahal Nissana. This settlement is in the Wadi el Fogeya in the Sinai and is also an MBI site. The similarity between these two settlements—and many other settlements in the Sinai and the Negev during this period—suggests that the MBI people migrated north from Sinai into Canaan. Perhaps these MBI people were Israelites or proto-Israelites who brought this distinctive settlement pattern with them to the Negev after their exodus from Egypt.
