'Ancestors' in the Bible

I said to the king, "May the king live forever! Why should my face not be sad when the city of my ancestors' burial site is ruined and her gates are consumed by fire?"

Then I said to the king, "If it pleases the king, and if your servant has [found] favor in your presence, [I ask] that you send me to Judah, to the city of my ancestors' burial sites, so that I may rebuild it."

Those of the seed of Israel separated themselves from all of the foreigners and stood and confessed their sins and the iniquities of their ancestors.

"You saw the misery of our ancestors in Egypt, and you heard their shout at the Red Sea.

"But they and our ancestors acted arrogantly and stiffened their neck and did not listen to your commandments.

You made their children numerous like the stars of the heavens and brought them to the land that you told their ancestors to enter in order to take possession.

"And now our God, the great, mighty, and awesome God who keeps [his] covenant and loyal love, do not belittle in your presence all of the hardship that is found in us, our kings, our officials, our priests, our prophets, our ancestors, and all of our people, from the days of the kings of Assyria until this day.

Our kings, our officials, our priests, and our ancestors did not keep your law and did not listen to your commandments and statutes that you declared to them.

Behold, we are slaves to this day, and the land that you have given to our ancestors to eat its fruits and [enjoy] its goodness--behold, we are slaves in it!

Did not your ancestors do this also, and our God brought on us all of this disaster and on this city [too]? Now you are adding fierce wrath on Israel by profaning the Sabbath!"
