In the biblical Book of Numbers, the Nehushtan (or Nohestan) (Hebrew: נחושתן or נחש הנחושת) was a bronze serpent on a pole which God told Moses to erect to prevent the Israelites who saw it of dying from the bites  of the "fiery serpents" which God had sent to punish them for speaking against God and Moses.
King Hezekiah later instituted a religious iconoclastic reform and destroyed "the brazen serpent that Moses had made; for unto those days the children of Israel did burn incense to it; [it was called|and he called it] Nehushtan." (2 Kings 18:4)
Snake cults had been well established in Canaan in the Bronze Age: archaeologists have uncovered serpent cult objects in Bronze Age strata at several pre-Israelite cities in Canaan: two at Megiddo, one at Gezer, one in the Kodesh Hakodashim (Holy of Holies) of the Area H temple at Hazor, and two at Shechem.
According to Lowell K. Handy, the Nehushtan may have been the symbol of a minor god of snakebite-cure within the Temple.
In the biblical story, following their Exodus from Egypt, the Israelites set out from Mount Hor, where Aaron was buried, to go to the Red Sea. However they had to detour around the land of Edom (Numbers 20:21, 25). Frustrated and impatient, they complained against Yahweh and Moses (Num. 21:4-5), and in response God sent "fiery serpents" among them. For the sake of the ones who were repentant, Moses was instructed by God to erect a "serpent of bronze" which was used to heal those who looked upon it (Numbers 21:4-9).
The term also appears in 2 Kings 18:4 in a passage describing reforms made by King Hezekiah, in which he tore down altars, cut down symbols of Asherah, destroyed the Nehushtan, and according to many Bible translations, gave it that name.
Regarding the passage in 2 Kings 18:4  M. G. Easton noted that "the lapse of nearly one thousand years had invested the 'brazen serpent' with a mysterious sanctity; and in order to deliver the people from their infatuation, and impress them with the idea of its worthlessness, Hezekiah called it, in contempt, 'Nehushtan,' a brazen thing, a mere piece of brass" 
In the Gospel of John, Jesus discusses his destiny with a Jewish teacher named Nicodemus and makes a comparison between the raising up of the Son of Man and the act of the serpent being raised up by Moses for the healing of the people.
Linguistic study of the term
The tradition of naming it Nehushtan is not considered to be any older than the time of Hezekiah.

- "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 Literature 58.2 (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".
