Exodus 34:5-7 (New International Version)

⁵ Then the LORD came down in the cloud and stood there with him and proclaimed his name, the LORD. ⁶ And he passed in front of Moses, proclaiming, "The LORD, the LORD, the compassionate and gracious God, slow to anger, abounding in love and faithfulness, ⁷ maintaining love to thousands, and forgiving wickedness, rebellion and sin. Yet he does not leave the guilty unpunished; he punishes the children and their children for the sin of the fathers to the third and fourth generation."
