2 Kings 18:4 reads, “[Hezekiah] 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 Nehushtan.”
We’re told in verse 3 that Hezekiah was a king who did right in the sight of the LORD, according to all that David his father did. Verse 4 is giving us a practical idea of what that meant. He removed high places, he broke images (those pesky 2nd commandment violations), and he broke to pieces the bronze serpent that Moses had made.
Hezekiah broke that which Moses made, and it is called good. Why? For up to that time, the Israelites had burned incense to it. Religious incense turned even something made by Moses into something that needed to be broken and trashed.
How interesting then that Eastern Orthodox congregations burn incense before images and icons every week and think it reverent.
