Sorry,but this is stupid as hell.
Now, you will tell us on no possible basis at all that the Jews on the same depicition commanded by GOD were totally faithful and later totally unfaithful but it had everything to do with God's depiction. MAKES NO SENSE>
Here are both in the Bible
God commands the depiction and it is rightfully used
, the Lord commands Moses to fashion a copper serpent and mount it on a pole. This command is surprising, because it seems to go against the Ten Commandments’ dictum not to make a “graven image” (Exod 20:4 RSV). Yet this image is not meant to be worshipped, but to be a means for the people to obtain divine aid.
Same depiction , exactly, wrongfully used.
Nehushtan (Heb. ןָּתְשֻחְנ) is the name of the copper serpent that King Hezekiah broke into pieces (II Kings 18:4). The name suggests both its serpentine shape (naḥash) as well as the material (neḥoshet) of which it was made. Since the smashing of the copper serpent parallels the shattering of the pillars and the cutting down of the Asherah (ibid.), it was probably located in the Temple court in Jerusalem. It was thus one of the cultic symbols of the people who assembled in the Temple courts. Like the local shrines (bamot), however, and like the two other objects named in the verse, it was illegitimate in the Deuteronomic view, in accordance with which Hezekiah abolished the former and destroyed the latter
