'Ancestors' in the Bible

Then Samuel said to the people, “The Lord, who appointed Moses and Aaron and who brought your ancestors up from the land of Egypt, is a witness.

Now present yourselves, so I may confront you before the Lord about all the righteous acts He has done for you and your ancestors.

“When Jacob went to Egypt, your ancestors cried out to the Lord, and He sent them Moses and Aaron, who led your ancestors out of Egypt and settled them in this place.

However, if you disobey the Lord and rebel against His command, the Lord’s hand will be against you and against your ancestors.
