'Ancestors' in the Bible

how our ancestors went down into Egypt, and we lived in Egypt a long time, and the Egyptians treated us and our ancestors badly.

"Aaron will be gathered to his ancestors, for he will not enter into the land I have given to the Israelites because both of you rebelled against my word at the waters of Meribah.

Remove Aaron's priestly garments and put them on Eleazar his son, and Aaron will be gathered to his ancestors and will die there."

When you have seen it, you will be gathered to your ancestors, as Aaron your brother was gathered to his ancestors.
