lo'-land (shephelah; compare Arabic sufalat, "the lowest part"): The western part of Palestine, including the maritime plain and the foothills. There has been an attempt to restrict the term to the foothills, at least as far as the more ancient documents are concerned, but there can be little doubt that the maritime plain should be included. the Revised Version (British and American) has "lowland" throughout for shephelah, while the King James Version has "low country" (2Ch 26:10; 28:18), "low plains" (1Ch 27:28; 2Ch 9:27), "plain" (Jer 17:26; Ob 1:19; Zec 7:7), "vale" or "valley" (De 1:7; Jos 9:1; 10:40).
