Exodus 34:5-7

5 Then the LORD came down in the cloud. He stood there with Moses and announced his name, The Lord.
6 As he passed in front of Moses, he called out. He said, "I am the Lord, the Lord. I am a God who is tender and kind. I am gracious. I am slow to get angry. I am faithful and full of love.
7 I continue to show my love to thousands of people. I forgive those who do evil. I forgive those who refuse to obey. And I forgive those who sin. But I do not let guilty people go without punishing them. I punish the children, grandchildren and great-grandchildren for the sin of their parents."
