Curses also run along blood lines. In Exodus 20:5-6, God warns the children of Israel not to follow false gods, saying, “You shall not bow down to them nor serve them. For I, the Lord your God, am a jealous God, visiting the iniquity of the fathers upon the children to the third and fourth generations of those who hate Me, but showing mercy to thousands, to those who love Me and keep My commandments.”
The word “iniquity” means to be bent toward a certain sin, and we see that the iniquity of the parents is carried on to the children to the third and fourth generations. So, a child will be bent like his or her parents, grandparents and great grandparents.
They will all have an inner inclination toward the same certain sinful habits. Lamentations 5:7 says, “Our fathers sinned and are no more, but we bear their iniquities.” In other words, even though they may be dead and in the grave, their iniquity is sticking with you.
