(Heb. sadeh), a cultivated field, but unenclosed. It is applied to any cultivated ground or pasture (Gen. 29:2; 31:4; 34:7), or tillage (Gen. 37:7; 47:24). It is also applied to woodland (Ps. 132:6) or mountain top (Judg. 9:32, 36; 2 Sam. 1:21). It denotes sometimes a cultivated region as opposed to the wilderness (Gen. 33:19; 36:35). Unwalled villages or scattered houses are spoken of as "in the fields" (Deut. 28:3, 16; Lev. 25:31; Mark 6:36, 56). The "open field" is a place remote from a house (Gen. 4:8; Lev. 14:7, 53; 17:5). Cultivated land of any extent was called a field (Gen. 23:13, 17; 41:8; Lev. 27:16; Ruth 4:5; Neh. 12:29).
