'Ancestors' in the Bible

"Be strong and courageous, because you'll be leading this people to inherit the land that I promised to give their ancestors.

For forty years the {Israelites} traveled in the wilderness until all the nation, the warriors that left Egypt, perished, because they did not listen to the voice of Yahweh. To them Yahweh swore that they would not see the land that he swore to their ancestors to give to us, a land flowing with milk and honey.

So Joshua told the Israelis, "How long will you delay invading and taking possession of the land that the LORD God of your ancestors has given you?

So the LORD gave all of the land to Israel that he had promised to give their ancestors, and they took possession and settled there in it.

The LORD gave them peace all around them, just as he had promised their ancestors. Not one of their enemies was able to oppose them the LORD placed all of their enemies under their control.

"That's also why we said, "It may be if they say these things to us and to our descendants in the future, so we will respond, "Look at this replica of the altar of the LORD that our ancestors made, not for burnt offerings or sacrifice, but rather as a reminder between us and you.

Joshua said to all the people, “This is what the Lord, the God of Israel, says: ‘Long ago your ancestors, including Terah, the father of Abraham and Nahor, lived beyond the Euphrates River and worshiped other gods.

"Long ago your ancestors lived beyond the Euphrates River, including Terah, father of both Abraham and Nahor, where they served other gods. Then I took your ancestor Abraham from the other side of the Euphrates River and led him through the entire land of Canaan. I multiplied his descendants, and gave him his son Isaac.

"Then I brought your ancestors out of Egypt, and you came to the Sea, and the Egyptians followed your ancestors with chariots and horsemen to the Reed Sea.

“Therefore, fear the Lord and worship Him in sincerity and truth. Get rid of the gods your fathers worshiped beyond the Euphrates River and in Egypt, and worship Yahweh.

If you think it's the wrong thing for you to serve the LORD, then choose for yourselves today whom you will serve the gods whom your ancestors served on the other side of the Euphrates River, or the gods of the Amorites in whose territories you are living. But as for me and my household, we will serve the LORD."

since the LORD our God is the one who brought us and our ancestors up from the land of Egypt, from a life of slavery. He did those great things right in front of us, preserving us along the way that we traveled and among all the nations through whose territory we passed.
