Genesis 17:15. And God said to Abraham, “As for Sarai your wife, you will not call her name Sarai, but her name will be Sarah.1 16. And I shall bless her and give you a son also from her. Yes, I will bless her and she will be a mother of nations; kings of peoples will be of her.”
Sarai/Sarah had quite some life, traveling into the unknown, struggling with being barren, but having promises from God that she would have a son. For years she lived as Sarai, meaning Abram’s princess. When Abram’s name was changed to Abraham in Genesis 17:5, the LORD also changed Sarai from being his Princess to Sarah, making her a full princess, no longer a possession of Abraham (Genesis 17:15). She put up with twice being taken into the harem of a king, once with pharaoh, and then later with Abimelech.
