Was Aaron a craftsman?
Yes, Aaron functioned as a craftsman. After receiving the golden earrings, he melted the gold and fashioned it with a graving tool, making the molten calf. The context states he worked the material and must have been a craftsman of some sort.
Les explains that Aaron took the golden earrings brought by the people, melted the gold, and fashioned it with a graving tool into a molten calf. He notes that Aaron 'worked that' and 'must have been a craftsman of some sort.' The context shows Aaron actively shaping the material, which supports the idea that he had craft skills.
