Exodus 34:6-7

American Standard Version

⁶ And Jehovah passed by before him, and proclaimed, Jehovah, Jehovah, a God merciful and gracious, slow to anger, and abundant in lovingkindness and truth; ⁷ keeping lovingkindness for thousands, forgiving iniquity and transgression and sin; and that will by no means clear the guilty, visiting the iniquity of the fathers upon the children, and upon the children’s children, upon the third and upon the fourth generation.
