Exodus 34:7; Exodus 34:9

7 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."

9 He said, "If now I have found favor in Your sight, O Lord , I pray, let the Lord go along in our midst, even though the people are so obstinate , and pardon our iniquity and our sin, and take us as Your own possession."
