Exodus 32:8-10

8They have turned aside quickly out of the way which I commanded them: they have made them a molten calf, and have worshipped it, and have sacrificed thereunto, and said, These be thy gods, O Israel, which have brought thee up out of the land of Egypt.

9And Yhwh said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:

10Now therefore let me alone, that my wrath may wax hot against them, and that I may consume them: and I will make of thee a great nation.
