Moses breaks the stone tablets of the law (Ex 32:15-32:24)

“Then Moses turned and went down from the mountain, carrying the two tablets of the covenant in his hands, tablets that were written on both sides, written on the front and the back.  The tablets were the work of God, and the writing was the writing of God, engraved upon the tablets.  When Joshua heard the noise of the people as they shouted, he said to Moses, ‘There is a noise of war in the camp.’  But Moses said, ‘It is not the sound made by victors, or the sound made by losers, it is the sound of revelers that I hear.’  As soon as he came near the camp and saw the calf and the dancing, Moses’ anger burned hot.  He threw the tables from his hand and broke them at the foot of the mountain.  He took the calf that they had made, burned it with fire, ground it to powder, scattered it on the water, and made the Israelites drink it.”

Moses descended the mountain, carrying the two stone tablets, written on both sides.  The tablets were the writings of God.  Joshua heard the noise in the camp.  Moses replied that is not the sound of winners or losers, but of revelers.  When Moses saw the calf and the dancing, he got angry and threw the tables on the ground and broke them at the foot of the mountain.  He took the calf and burned it and ground into powder.  He then scattered the powder on the water and made the Israelites drink it.   Just after calming Yahweh, Moses got angry.

“Moses said to Aaron, ‘What did this people do to you that you have brought a great sin upon them?’  Aaron said, ‘Do not let the anger of my lord burn hot.  You know the people.  They are bent on evil.’  They said to me, ‘Make us gods, who shall go before us.  As for this Moses, the man who brought us up out of the land of Egypt, we do not know what has become of him.’  So I said to them, ‘Whoever has gold take it off.’  So they gave it to me, and I threw it into the fire, and out came this calf.’”

Moses was angry with Aaron, since Aaron and his sons were to play such a big role in future worship services.  Aaron blamed the people because they were bent on evil. Then Aaron explained how he made the golden calf.  Moses acted like Yahweh had acted to him and got angry with Aaron.
