Exodus 32:28-30

New Century Version

²⁸ The people from the family of Levi obeyed Moses, and that day about three thousand of the Israelites died. ²⁹ Then Moses said, “Today you have been given for service to the Lord. You were willing to kill your own sons and brothers, and God has blessed you for this.”

³⁰ The next day Moses told the people, “You have done a terrible sin. But now I will go up to the Lord. Maybe I can do something so your sins will be removed.”
