ASOR (Hebr. for " ten ")  , an instrument " of ten strings " mentioned in the Bible, about which authors are not agreed . The word occurs only three times in the Bible, and has not been traced elsewhere . In Psalm xxxiii . 2 the reference is to " kinnor, nebel and asor "; in Psalm xcii . 3, to " nebel and asor "; in Psalm cxliv. to " nebel-asor." In the English version asor is translated " an instrument of ten strings," with a marginal note " omit " applied to " instrument." In the Septuagint, the word being derived from a root signifying " ten," the Greek is iv SeuaxopScu or 1,taXT17pcov Serckopbov, in the Vulgate in decachordo psalterio . Each time the word asor is used it follows the word nebel (see PSALTERY), and probably merely indicates a variant of the nebel, having ten strings instead of the customary twelve assigned to it by Josephus (Antiquities, vii . 12 . 3) .
