Chp 32 verse 15 - Chp. 33 verse 16: Moshe comes down from the mountain, when he sees the calf he becomes angry and breaks the tablets. He burns the calf and makes them drink from its ashes. Aaron then explains what occurred during his absence. Moshe gathers the tribe of Levi and they kill those that worshiped the calf. He begs Hashem to forgive the people or erase his name from His book. Chp. 33, Hashem tells Moshe to leave the mountain and an angel not He, would lead them to the land. Moshe moves his tent outside the camp. Moshe tells Hashem that if HE doesn't lead them then they don't want to leave.
