Exodus 34:7
Brenton's English Septuagint · Berean Standard Bible
and keeping justice and mercy for thousands, taking away iniquity, and unrighteousness, and sins; and he will not clear the guilty; bringing the iniquity of the fathers upon the children, and to the children's children, to the third and fourth generation.
maintaining loving devotion to a thousand generations, forgiving iniquity, transgression, and sin. Yet He will by no means leave the guilty unpunished; He will visit the iniquity of the fathers on their children and grandchildren to the third and fourth generations.”
