'Iniquity' in the Bible

keeping loyal love to the thousands, forgiving iniquity and transgression and sin, and he does not leave utterly unpunished, punishing [the] guilt of fathers on sons and on sons of sons on third and fourth [generations]."

And he said, "Please, if I have found favor in your eyes, Lord, let my Lord, please, go among us--indeed it is a stiff-necked people--and forgive our iniquity and our sin and {take us as your possession}."
