Exodus 32:2-8

2And Aaron said to them, Break off the golden earrings, which are in the ears of your wives, of your sons, and of your daughters, and bring them to me. 3And all the people broke off the golden earrings which were in their ears, and brought them to Aaron. 4And he received them at their hand, and fashioned it with an engraving tool, after he had made it a molten calf: and they said, These are thy gods, O Israel, which brought thee out of the land of Egypt. 5And when Aaron saw it, he built an altar before it; and Aaron made proclamation, and said, To morrow is a feast to the LORD. 6And they rose early on the next morning, and offered burnt offerings, and brought peace offerings; and the people sat down to eat and to drink, and rose up to play.

7And the LORD said to Moses, Go, go down; for thy people, which thou broughtest out of the land of Egypt, have corrupted themselves : 8They have turned aside quickly from the way which I commanded them: they have made them a molten calf, and have worshipped it, and have sacrificed to it, and said, These are thy gods, O Israel, which have brought thee out of the land of Egypt.
