Exodus 32:2-5

32:2 So Aaron said to them, “Break off the gold earrings that are on the ears of your wives, your sons, and your daughters, and bring them to me.” 32:3 So all the people broke off the gold earrings that were on their ears and brought them to Aaron. 32:4 He accepted the gold from them, fashioned it with an engraving tool, and made a molten calf. Then they said, “These are your gods, O Israel, who brought you up out of Egypt.”

32:5 When Aaron saw this, he built an altar before it, and Aaron made a proclamation and said, “Tomorrow will be a feast to the Lord.”

Exodus 32:21-24

32:21 Moses said to Aaron, “What did this people do to you, that you have brought on them so great a sin?” 32:22 Aaron said, “Do not let your anger burn hot, my lord; you know these people, that they tend to evil. 32:23 They said to me, ‘Make us gods that will go before us, for as for this fellow Moses, the man who brought us up out of the land of Egypt, we do not know what has happened to him.’ 32:24 So I said to them, ‘Whoever has gold, break it off.’ So they gave it to me, and I threw it into the fire, and this calf came out.”
