'Fourth Generation' in the Bible

you shall not bow yourself down to them, nor serve them, for I, Yahweh your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and on the fourth generation of those who hate me,

keeping loving kindness for thousands, forgiving iniquity and disobedience and sin; and that will by no means clear the guilty, visiting the iniquity of the fathers on the children, and on the children's children, on the third and on the fourth generation."
