30 The next day Moses said to the people, “You have committed a great sin. But now I will go up to the LORD; perhaps I can make atonement for your sin.”
31 So Moses went back to the LORD and said, “Oh, what a great sin these people have committed! They have made themselves gods of gold.
32 But now, please forgive their sin–but if not, then blot me out of the book you have written.”
33 The LORD replied to Moses, “Whoever has sinned against me I will blot out of my book. (Exo 32:30-33)
