Duke
Duke (from the Latin dux, a leader) stands in our version for two Hebrews terms: אִלּוּŠ (see a dissertation on this word by Sprenger, in the Zeitschr. f. deutsch. nmorgen. Gesellschvft, XII, 2:316), alluph', a leader, which, besides its ordinary sense of guide or friend, is used technically of the phylarch, or head of a tribe or nation, especially of the Edomitish chieftains (Ge 36:15-43; Ex 15:15; 1Ch 1:51-54), rarely of the Jews ("governor," Zec 9:7; Zec 12:5-6), and once of chiefs in general ("captain," Jer 13:21); also נָסַיך, nasik', one anointed (usually in poetry), spoken of the magnates of Sihon, perhaps by a paraphrase for that king himself (Jos 13:21), elsewhere of other "princes" (Ps 83:11; Eze 32:30; Da 11:8; "principal men," Mic 5:5).
