'Fathers' in the Bible

It is he who will go as a forerunner before Him in the spirit and power of Elijah, to turn the hearts of the fathers back to the children, and the disobedient to the attitude of the righteous [which is to seek and submit to the will of God]—in order to make ready a people [perfectly] prepared [spiritually and morally] for the Lord.”

Woe to you! For you repair or build tombs for the prophets, and it was your fathers who killed them.

So you are witnesses and approve the deeds of your fathers, because they [actually] killed them, and you repair or build their tombs.
