Exodus 32:3-6
And all the people brake off the golden earrings which were in their ears, and brought them unto Aaron.
And
he received them at their hand, and fashioned it with a graving tool,
after he had made it a molten calf: and they said, These be thy gods, O
Israel, which brought thee up out of the land of Egypt.
And when Aaron saw it, he built an altar before it; and Aaron made proclamation, and said, To morrow is a feast to the LORD.
And
they rose up early on the morrow, and offered burnt offerings, and
brought peace offerings; and the people sat down to eat and to drink,
and rose up to play.
