Exodus 32:14, 33-34

So the LORD relented from the harm which He said He would do to His people.

And the LORD said to Moses, “Whoever has sinned against Me, I will blot him out of My book. Now therefore, go, lead the people to the place of which I have spoken to you. Behold, My Angel shall go before you. Nevertheless, in the day when I visit for punishment, I will visit punishment upon them for their sin.”
