'Younger' in the Bible

And thine elder sister is Samaria, she and her daughters, Who is dwelling at thy left hand, And thy younger sister, who is dwelling on thy right hand, is Sodom and her daughters.

And thou hast remembered thy ways, And thou hast been ashamed, In thy receiving thy sisters -- Thine elder with thy younger, And I have given them to thee for daughters, And not by thy covenant.
