Exodus 32:3-5

Revised Standard Version

³ So all the people took off the rings of gold which were in their ears, and brought them to Aaron. ⁴ And he received the gold at their hand, and fashioned it with a graving tool, and made a molten calf; and they said, “These are your gods, O Israel, who brought you up out of the land of Egypt!” ⁵ When Aaron saw this, he built an altar before it; and Aaron made proclamation and said, “Tomorrow shall be a feast to the Lord.”
