'Iniquity' in the Bible

You shall not worship them nor serve them; for I, the Lord your God, am a jealous (impassioned) God [demanding what is rightfully and uniquely mine], visiting (avenging) the iniquity (sin, guilt) of the fathers on the children [that is, calling the children to account for the sins of their fathers], to the third and fourth generations of those who hate Me,

It shall be on Aaron’s forehead, and Aaron shall take away the guilt from the holy things which the sons of Israel dedicate, with regard to all their holy gifts. It shall always be on his forehead, so that they may be accepted before the Lord.

The various articles of clothing shall be on Aaron and on his sons when they enter the Tent of Meeting, or when they approach the altar [of incense] to minister in the Holy Place, so that they do not incur guilt and die. It shall be a statute forever to Aaron and to his descendants after him.

keeping mercy and lovingkindness for thousands, forgiving iniquity and transgression and sin; but He will by no means leave the guilty unpunished, visiting (avenging) the iniquity (sin, guilt) of the fathers upon the children and the grandchildren to the third and fourth generations [that is, calling the children to account for the sins of their fathers].”

And he said, “If now I have found favor and lovingkindness in Your sight, O Lord, let the Lord, please, go in our midst, though it is a stiff-necked (stubborn, rebellious) people, and pardon our iniquity and our sin, and take us as Your possession.”
