^"Modern exegesis holds two different opinions in regard to the meaning of the word "Nehushtan," which is explained either as denoting an image of bronze, and as entirely unconnected with the word "naḥash" (serpent), or as a lengthened form of "naḥash" (comp. νεεσθάν in the Septuagint), and thus as implying that the worship of serpents was of ancient date in Israel. The assumption that the tradition about "Nehushtan" is not older than the time of Hezekiah is, however, not contested." Jewish Encyclopedia, s.v. "Nehushtan"; H. H. Rowley, "Zadok and Nehushtan" Journal of Biblical Literature58.2 (June 1939:113-141) p. 132 observes, "We have no record of this Brazen Serpent before this time, save for the obvious aetiological story in Num. 8 f, which states that this sacred symbol had its origin in the Mosaic age".
