Exodus 34:5-7

New Catholic Bible

⁵ The Lord came down in a cloud and stood with him there and proclaimed the name of the Lord. ⁶ The Lord passed in front of him proclaiming, “The Lord, the Lord, a compassionate and gracious God, slow to anger and abounding in steadfast love and fidelity, ⁷ who shows mercy to thousands. He forgives iniquity and transgression and sin, but will by no means forgive the iniquity of the fathers, visiting it upon their sons and their sons’ sons, to the third and fourth generation.”
