The people of Samaria travel over to Crime City to worship the golden calf-god. They go all out, prancing and hollering, taken in by their showmen priests. They act so important around the calf-god, but are oblivious to the sham, the shame.
They have plans to take it to Assyria, present it as a gift to the great king. And so Ephraim makes a fool of himself, disgraces Israel with his stupid idols.
