Idolatry was bad enough, but national idolatry
on such a scale so soon after formally accepting the privileges and
responsibilities of being called by Jehovah to be a people uniquely his own
gave the lie to everything Israel was supposed to stand for. It made a mockery
of Israel’s promises and a joke of its testimony to the nations around it. God struck the people with a plague, and Moses struck them with the sword of the House of Levi, killing
three thousand.
Basically, a disaster.
