'Younger' in the Bible

And thine elder sister is Samaria, she and her daughters that dwell at thy left hand: and thy younger sister, that dwelleth at thy right hand, is Sodom and her daughters.

Then thou shalt remember thy ways, and be ashamed, when thou shalt receive thy sisters, thine elder and thy younger: and I will give them unto thee for daughters, but not by thy covenant.

Oholah was the name of the older and Oholibah the name of her younger sister. They became mine, and gave birth to sons and daughters. Oholah is Samaria and Oholibah is Jerusalem.
