Exodus 32:1-4

1And when the people saw that Moses delayed to come down from the mountain, the people collected together to Aaron, and said to him, Up, make us a 1god, who will go before us; for this Moses, the man that has brought us up out of the land of Egypt, — we do not know what is become of him!

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 2god, Israel, who has brought thee up out of the land of Egypt!
