Exodus 32:33-35 New Revised Standard Version (NRSV)
33 But the Lord said to Moses, “Whoever has sinned against me I will blot out of my book. 34 But now go, lead the people to the place about which I have spoken to you; see, my angel shall go in front of you. Nevertheless, when the day comes for punishment, I will punish them for their sin.”
35 Then the Lord sent a plague on the people, because they made the calf—the one that Aaron made.
