Exodus 32:33-35

32:33 The Lord said to Moses, “Whoever has sinned against me – that person I will wipe out of my book. 32:34 So now go, lead the people to the place I have spoken to you about. See, my angel will go before you. But on the day that I punish, I will indeed punish them for their sin.”

32:35 And the Lord sent a plague on the people because they had made the calf – the one Aaron made.
