This young bull is made in imitation of the Canaanite fertility gods. The bull is a prominent symbol of Baal. Creating this idol requires a long, intentional process of collecting enough precious metal for a statue, melting it down and purifying it, pouring it into a mold that also has to be designed and crafted, and making sure the statue cools evenly so that it doesn’t break apart. (Perhaps the Israelites learned these crafts by observation or practice in Egypt.) This was no casual slip into an unintentional religious compromise. This is a deliberate embrace of a god other than the Lord, right at the moment when He is drawing up His covenant of love with Israel. They are as unfaithful to the Lord as a person who has an affair while on his honeymoon!
