'Transgression' in the Bible

Be on your guard before him and obey his voice; do not be rebellious toward him, for he will not pardon your transgression, since My name is in him.

who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations.”
