Sabbatic River, a stream of Palestine, described by ancient writers as flowing only on the Sabbath day (Reland, Paloest. p. 291). Josephus locates it between Arce and Raphanaca (War, 7, 24). Thomson thinks that the intermittent fountain of Nebo el-Fuar, in the valley of Mar Jirius, west of Kulat Husn, near Tripoli, may have been the origin of the fountain, as it seems to contain a siphon for carrying off the overflow of the water (Land and Book, 1, 496 sq.).
