'Ancestors' in the Bible

The blessings of thy father surpass the blessings of my ancestors, Unto the bounds of the everlasting hills: They shall be on the head of Joseph, And on the crown of the head of him that was separated from his brethren.

But I will remember toward them the covenant with their ancestors whom I brought forth out of the land of Egypt before the eyes of the nations, that I might be their God: I am Jehovah.
