1911 Encyclopædia Britannica/Asor
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 ἐν δεκαχορδῷ or ψαλτήριον δεκάχορδον, 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).
