Was the golden calf an Egyptian god?
Yes. The golden calf was an Egyptian god as well, the calf or ox, one of many. The Israelites were used to such gods in Egypt, where everything was a god, and that influence had rubbed off on them, so they asked Aaron to make gods to go before them.
Les explains that the people were accustomed to gods in Egypt, where everything was a god, and that some of that had rubbed off on the Israelites. They gathered under Aaron and asked him to make gods to go before them. Aaron took their golden earrings, melted the gold, and fashioned a molten calf with a graving tool. Les notes this calf, ox, or whatever, was an Egyptian god as well, one of many. Aaron then declared, 'These be thy gods, O Israel,' but Les points out that was a lie; the golden calf had nothing to do with bringing them through the Red Sea. Les also observes that men wearing earrings was not new, as they did it way back then.
And he received them at their hand, and fashioned it with a graving tool, after he had made it a molten calf: and they said, These be thy gods, O Israel, which brought thee up out of the land of Egypt.
