Lifted up for healing in the wilderness, smashed as an idol by Hezekiah, claimed by Jesus as a type of the cross — the Bible's own case study in how a God-given symbol can be both used and abused.

Origin
Fully biblical: God commands Moses to make a bronze serpent and set it on a pole; the bitten who look at it live (Numbers 21:4–9). Centuries later it has become an idol receiving incense — named Nehushtan — and the reforming king Hezekiah destroys it (2 Kings 18:4). Jesus then claims the original event as a type of his own lifting up (John 3:14–15), two verses before John 3:16.
The Mishnah (Rosh Hashanah 3:8 — rabbinic tradition, not Scripture) asks how a serpent could heal and answers: it did not — looking up turned Israel's heart to their Father in heaven. The object was a pointer, never a power.
Early Church
Read through John 3 as a type of the crucifixion: the image of the curse, lifted up, becomes the cure. Justin Martyr and Barnabas (non-canonical writings, plainly noted) both press the typology.
Orthodox
A classic Old Testament prefiguration of the Cross, appearing in iconographic programs of the crucifixion; also standing proof that God himself commanded a fashioned image to serve faith — a datum in the icon debate.
Catholic
Type of the crucifix lifted before the faithful; Hezekiah's reform shows the abuse of images is corrected by right use, not necessarily by abolition.
Protestant
The whole arc is the argument: even a God-commanded image, given time, drew incense — and the faithful response was to break it. Nehushtan is the standing caution against the religious use of images drifting into veneration.
Look and live
The serpent — the very form of the plague — is lifted on a pole, and looking at it heals. The logic is vicarious and visual: the curse displayed becomes the cure received by faith. Jesus reads his own death there: 'as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up' (John 3:14).
The biography of a symbol
No other biblical object traces the full arc so cleanly: commanded by God → instrument of salvation → relic → idol → destroyed by a king the text praises for it. Scripture itself teaches that a symbol's origin does not immunize its future. Every tradition reads its own lesson here, and the honest summary is that both lessons are in the text: God uses material signs, and material signs can rot into idols.
Pastoral Caution
Nehushtan is the permanent question mark beside every devotional object: is this still a window to God, or has it become the thing itself? When a symbol starts receiving what belongs to God, Scripture's precedent is Hezekiah's hammer.
