Jeroboam ben Nebat and the Golden Calves

The sin that bears his name ran on for more than two centuries—as long as the Northern Kingdom stood.

Jeroboam reasoned like a politician: three times a year the people would go up to Jerusalem, see the Temple and a king of David's line—and one day they would not come back. So he cast two golden calves and placed them at the two ends of his kingdom, in Bethel and in Dan, saying, "It is too much for you to go up to Jerusalem; behold your gods, O Israel, who brought you up out of Egypt." He built shrines on high places, appointed priests who were not Levites, invented a festival on the fifteenth of the eighth month—a copy of Sukkot shifted by a month—and posted guards on the roads south.

At Bethel, as the king stood at the altar, a man of God from Judah foretold that a king named Josiah would one day burn the bones of these priests on it. Jeroboam stretched out his hand to seize him and it withered; the altar split. The prophecy came true, almost word for word, three centuries later.

The Levites and the faithful moved south. From then on, "he walked in the way of Jeroboam ben Nebat, who caused Israel to sin" is the verdict passed on king after king in the north.

Academic history dates this event differently. In the age of the kings the divergence is not the one familiar from the Persian period, where Seder Olam runs about a hundred and sixty-five years short. Here academic chronology reckons some reigns as overlapping — father and son on the throne together — so its span from the division of the kingdom to the destruction of the Temple comes out nearly three decades shorter. The gap therefore grows: a hundred and thirty-five years at the division, a hundred and fifty-four at Sennacherib, a hundred and sixty-four at the destruction. The anchors of the academic count are external documents: the battle of Qarqar (853), Jehu's tribute on the Black Obelisk (841), the fall of Samaria (722), Sennacherib's campaign (701), Megiddo and Nebuchadnezzar's campaigns in the Babylonian Chronicles (609, 605, 597). Both dates appear on the timeline when the divergence layer is on.
