=Its Northern and Western Divisions.= The hill country immediately to the south of Judah is fairly fertile. Cultivated fields are found in the valleys and terraces on the hillsides, even as far as the Wady Sheba and the famous desert sanctuary of Beersheba. To the south and west of Beersheba are found the ruins of many cities, which evidently enjoyed high prosperity during the later Roman period. Here, as throughout most of the South Country, rain falls during the winter season, so that where the water is stored, irrigation is possible. A few springs also furnish a perennial supply of water. Thus under a strong stable government, the northern and northwestern portions of the South Country are capable of supporting a large, semi-agricultural population. By nature, however, it is the land of the nomad. Throughout most of its history, the Bedouin have dominated it as they do to-day. When undeveloped by irrigation, its hills and valleys are covered in springtime by a green herbage, which disappears, except in some secluded glens, before the glaring heat of summer. To the south, the Negeb at last descends to the great barren desert of Tîh, across which ran the highways to Egypt, to Arabia, and to Babylonia. =Its Central and Eastern Divisions.= The central and eastern part of this South Country is dry and barren and occupied only by fierce Bedouin tribes. The absence of water, the ruggedness of its mountain ranges, and the fierceness of its population have rendered it almost impassable throughout most of its history. Many portions of it are still unexplored. Thus, on its southern boundary, Judah was thoroughly protected from the advance of hostile armies. At the same time, from this South Country there came a constant infiltration of the population and ideas of the desert, which left a deep imprint upon the character of the southern Israelites.
