Exodus 32:30-33

30And it came to pass on the next day, that Moses said to the people, Ye have sinned a great sin: and now I will go up to the LORD; perhaps I shall make an atonement for your sin. 31And Moses returned to the LORD, and said, O, this people have sinned a great sin, and have made them gods of gold. 32Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written. 33And the LORD said to Moses, Whoever hath sinned against me, him will I blot out of my book.
