Exodus 32:2-7

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.

7Then Jehovah said to Moses, Away, go down! for thy people, which thou hast brought out of the land of Egypt, is acting corruptly.
