Exodus 13 - The Golden Calf

When Moses delays in coming down from Mt. Sinai, the people demand an idol of gods to go before them. Aaron makes a bull out of the people's gold, in the form of some of the Canaanite gods, and declares it to be the god that brought the Hebrews out of Egypt. God proposes to kill the Hebrews and make a great nation out of Moses, but Moses intercedes for the people. God, through Moses, directs the tribe of Levi to slay those notorious in the production of the golden calf, and for that, the tribe of Levi is ordained for service to the Lord. God tells the people that He will not be among them, for they are a stiff-necked people and He would consume them. He orders the people to take off their ornaments and mourn, and God resides in the tent of meeting outside of the camp.
