'Fathers' in the Bible

“Do we not all have one father? Has not one God created us? Why do we deal treacherously each against his brother so as to profane the covenant of our fathers?

“From the days of your fathers you have turned aside from My statutes and have not kept them. Return to Me, and I will return to you,” says the Lord of hosts. “But you say, ‘How shall we return?’

He will restore the hearts of the fathers to their children and the hearts of the children to their fathers, so that I will not come and smite the land with a curse.”
