The Sins of Parents

Ezekiel 18:18-19

18  As for his father, because he cruelly oppressed, spoiled his brother by violence, and did that which is not good among his people, lo, even he shall die in his iniquity. 
19  Yet say ye, Why? doth not the son bear the iniquity of the father? When the son hath done that which is lawful and right, and hath kept all my statutes, and hath done them, he shall surely live.
