Numbers 14:18; Numbers 14:33

18 'The LORD is slow to anger and abundant in lovingkindness, forgiving iniquity and transgression; but He will by no means clear the guilty, visiting the iniquity of the fathers on the children to the third and the fourth generations.'

33 'Your sons shall be shepherds for forty years in the wilderness, and they will suffer for your unfaithfulness, until your corpses lie in the wilderness.
