Exodus 32:29-33

For Moses had said, Consecrate yourselves to day to the LORD, even every man upon his son, and upon his brother; that he may bestow upon you a blessing this day.

And it came to pass on the morrow, that Moses said unto the people, Ye have sinned a great sin: and now I will go up unto the LORD; peradventure I shall make an atonement for your sin.

And Moses returned unto the LORD, and said, Oh, this people have sinned a great sin, and have made them gods of gold.

Yet now, if thou wilt forgive their sin—; and if not, blot me, I pray thee, out of thy book which thou hast written.

And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book.
