Isaiah: God appears to get rather testy about the misuse of His name. It so important that He included that offense in the second of His Ten Commandments. By this time the Northern Kingdom (Israel) had been carried off by the Assyrians. Jeroboam (I), the first king of the Northern Kingdom, had set up a couple of golden calves so his people would not worship, and perhaps remain, in Jerusalem. This was a continual act of blasphemy such so that it became known as the “sin of Jeroboam.” Jeremiah tells us later that Judah was much worse.
