As Moses beheld the children of Israel shouting and dancing in an excited manner, in imitation of the idolatrous feasts and idol-worshipers of Egypt, so unlike the reverential worship of God, he was overwhelmed. He had just come from the presence of God’s glory, and although he had been warned of God that the people had corrupted themselves, had made an idol and had sacrificed to it, yet he was in a measure unprepared for the dreadful exhibition which he witnessed of the degradation of Israel. He threw down the tables of stone in utter discouragement and wrath, because of Israel’s great sin before God. (3SG 279.1) MC VC

The act of Moses in burning the calf and grinding it to powder, and making them drink of it, was to show them the utter worthlessness of the God which they had been worshiping—that their God had no power at all. Men could burn it in the fire, grind it to powder and drink it without receiving any injury therefrom. He asked them how then could they expect such a God to save them, or do them any good, or any evil? Then he rehearsed to them the exhibitions which they had witnessed of the unlimited power, glory, and majesty of the living God. (3SG 279.2) MC VC
