Because the people of Israel had worshipped the golden calf, Moses went up the mountain and begged the Lord to forgive them. He said, “O Lord, your people have sinned against you. If you will forgive their sins …” He couldn’t continue, but finally said, “If you can’t forgive them, blot me out of your book.”
The Lord said, “I’m not blotting your name out of my book, but I will blot out the names of the people who sinned against me.” Then God struck the people with a plague and many died.
