Exodus 32:28-35 HNV

28 The sons of Levi did according to the word of Moshe: and there fell of the people that day about three thousand men.
29 Moshe said, "Consecrate yourselves today to the LORD, yes, every man against his son, and against his brother; that he may bestow on you a blessing this day."
30 It happened on the next day, that Moshe said to the people, "You have sinned a great sin. Now I will go up to the LORD. Perhaps I shall make atonement for your sin."
31 Moshe returned to the LORD, and said, "Oh, this people have sinned a great sin, and have made themselves gods of gold.
32 Yet now, if you will, forgive their sin-- and if not, please blot me out of your book which you have written."
33 The LORD said to Moshe, "Whoever has sinned against me, him will I blot out of my book.
34 Now 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 punish, I will punish them for their sin."
35 The LORD struck the people, because they made the calf, which Aharon made.
