Exodus 32:3-5

New Revised Standard Version, Anglicised Catholic Edition

³ So all the people took off the gold rings from their ears, and brought them to Aaron. ⁴ He took the gold from them, formed it in a mould,^[a] and cast an image of a 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 festival to the Lord.’
