This guy's carving a big ol' golden sex god cow, although in the Bible it is Mose's brother Aaron who carves the golden calf false idol.

It is possible that this guy's name is "Hezron", an associate of Moses, but Hezron from the Bible seemingly was not a carver of graven images, and the way Homer says it omits the H to my hearing - and Frinkiac backs me up on this.
I do admire the devotion to their religion that these guys have. As soon as they are told "don't do that!" by their God, they immediately give up their primary identifiers, their raison d'être.
