'Younger' in the Bible

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

And thou shalt remember thy ways, and be confounded, when thou shalt receive thy sisters who are older than thou, together with those who are younger than thou; for I will give them unto thee for daughters, but not by virtue of thy covenant.
