Exodus 32:31

29Moses said, “Consecrate yourselves today to the LORD, for every man was against his son and against his brother, that he may give you a blessing today.”

30On the next day, Moses 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.”

31Moses returned to the LORD, and said, “Oh, this people have sinned a great sin, and have made themselves gods of gold.

32Yet now, if you will, forgive their sin—and if not, please blot me out of your book which you have written.”

33The LORD said to Moses, “Whoever has sinned against me, I will blot him out of my book.
