'Younger' in the Bible

"Your mother was a Hittite and your father was an Amorite. Your elder sister was Samaria. She and her daughters lived in the north, while your younger sister who lived in the south with her daughters was Sodom.

Then you'll remember your behavior and be ashamed when you greet your sisters your elder sister and your younger sister. I'll give them to you as daughters, but not on account of my covenant with you.
