He removed the high places, and brake the images, and cut down the groves, and brake in pieces the brasen serpent that Moses had made: for unto those days the children of Israel did burn incense to it: and he called it {b} Nehushtan.

(b) That is a piece of brass: thus he calls the serpent by contempt, which even though it was set up by the word of God, and miracles were wrought by it, when it was used for idolatry this good king destroyed it, not thinking it worthy to be called a serpent, but a piece of brass.

Wesley's Notes

18:4 Serpent - The most of them, or such as the people most frequented: for all were not taken away, chap.23:13,14, tho' his own father had set them up. We must never dishonour God, in honour to our earthly parents. Brazen serpent - Which had been hitherto kept as a memorial of God's mercy; but being now commonly abused to superstition, was destroyed. To it - Not doubtless as to a god, but only as to an instrument of God's mercy, by and through which, their adoration was directed to God, and given to that only for God's sake. Nehushtan - He said, this serpent, howsoever formerly honoured, and used by God as a sign of his grace, yet now it is nothing but a piece of brass which can do you neither good nor hurt.

Jamieson-Fausset-Brown Bible Commentary

2Ki 18:4-37. He Destroys Idolatry.

4. He removed the high places and brake the images, &c.-The methods adopted by this good king for extirpating idolatry, and accomplishing a thorough reformation in religion, are fully detailed (2Ch 20:3; 31:19). But they are indicated very briefly, and in a sort of passing allusion.

brake in pieces the brazen serpent-The preservation of this remarkable relic of antiquity (Nu 21:5-10) might, like the pot of manna and Aaron's rod, have remained an interesting and instructive monument of the divine goodness and mercy to the Israelites in the wilderness: and it must have required the exercise of no small courage and resolution to destroy it. But in the progress of degeneracy it had become an object of idolatrous worship and as the interests of true religion rendered its demolition necessary, Hezekiah, by taking this bold step, consulted both the glory of God and the good of his country.

unto those days the children of Israel did burn incense to it-It is not to be supposed that this superstitious reverence had been paid to it ever since the time of Moses, for such idolatry would not have been tolerated either by David or by Solomon in the early part of his reign, by Asa or Jehoshaphat had they been aware of such a folly. But the probability is, that the introduction of this superstition does not date earlier than the time when the family of Ahab, by their alliance with the throne of Judah, exercised a pernicious influence in paving the way for all kinds of idolatry. It is possible, however, as some think, that its origin may have arisen out of a misapprehension of Moses' language (Nu 21:8). Serpent-worship, how revolting soever it may appear, was an extensively diffused form of idolatry; and it would obtain an easier reception in Israel because many of the neighboring nations, such as the Egyptians and Phonicians, adored idol gods in the form of serpents as the emblems of health and immortality.

Matthew Henry's Concise Commentary

18:1-8 Hezekiah was a true son of David. Some others did that which was right, but not like David. Let us not suppose that when times and men are bad, they must needs grow worse and worse; that does not follow: after many bad kings, God raised one up like David himself. The brazen serpent had been carefully preserved, as a memorial of God's goodness to their fathers in the wilderness; but it was idle and wicked to burn incense to it. All helps to devotion, not warranted by the word of God, interrupt the exercise of faith; they always lead to superstition and other dangerous evils. Human nature perverts every thing of this kind. True faith needs not such aids; the word of God, daily thought upon and prayed over, is all the outward help we need.
