Exodus 34:4-7

So he cut out two stone tablets like the former ones, and Moses rose up early in the morning and went up to Mount Sinai, as the LORD had commanded him, and he took two stone tablets in his hand. The LORD descended in the cloud and stood there with him as he called upon the name of the LORD. Then the LORD passed by in front of him and proclaimed, “The LORD, the LORD God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations.”
