(Hebrews Dophkah', דָּפְקָה, according to Gesenius, a knocking; accord. to Fü rst, cattle-driving; Sept. ῾Ραφακά, by error of ר for ד; Vulg. Dapaca), the eighth place of encampment of the Israelites in coming out of Egypt (Numbers 33:12). It was situated in the desert of Sin, on the eastern shore of the western arm of the Red Sea, probably at the mouth of Wady Feiran. (See EXODE). Pococke (East, 1:235) thinks it lies east of Thor, in Wady Hibran; but this is apparently conjecture. Furst (Hebrews Handw. s.v.), after Seetzen (Zach's Correspond. 27:71), says it is the modern el- Tobbacha; which, if the el-Tubukah of Robinson (Res. 2:388, 648), is far away, and probably the ancient Tagoba (q.v.); but if in the valley Kineh (Keil, Exodus page76), would be precisely opposite our location (Robinson, 1:121, 122).
