'Transgression' in the Bible

Be on your guard before Him, listen to and obey His voice; do not be rebellious toward Him or provoke Him, for He will not pardon your transgression, since My Name (authority) is in 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].”
