18:4 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.
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.
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.
