'Transgression' in the Bible

Take ye heed before him, and hearken unto his voice; provoke him not; for he will not pardon your transgression: for my name is in him.

keeping lovingkindness for thousands, forgiving iniquity and transgression and sin; and that will by no means clear the guilty , visiting the iniquity of the fathers upon the children, and upon the children's children, upon the third and upon the fourth generation.
