Exodus 32:2-6

2And Aaron said to them, Break off the golden rings that are in the ears of your wives, of your sons, and of your daughters, and bring [them] to me.

3Then all the people broke off the golden rings that were in their ears, and brought [them] to Aaron.

4And he took [them] out of their hand, and fashioned it with a chisel and made of it a molten calf: and they said, This is thy 1god, Israel, who has brought thee up out of the land of Egypt!

5And Aaron saw [it], and built an altar before it; and Aaron made a proclamation, and said, To-morrow is a feast to Jehovah!

6And they rose up early on the morrow, and offered up burnt-offerings, and brought peace-offerings; and the people sat down to eat and to drink, and rose up to sport.
