Ezekiel 16:46 - Ellicott's Commentary On The Whole Bible

Thine elder sister. — The words elder and younger mean, literally, greater and smaller. They thus come, like the Latin major and minor, to be used for older and younger; but still their original and most common meaning, which should be retained here, is greater and smaller. Chronologically, Sodom was not younger than Jerusalem, nor is there evidence that Samaria was older. The terms are to be understood of Samaria as the capital of the far larger northern kingdom, and of Sodom as a single city of no great population. The Orientals, in describing geographical positions, considered themselves as facing the east, and hence Samaria (at the north) was on the left, and Sodom on the right. Sodom is spoken of poetically as if still in existence. They were both the spiritual sisters of Judah, just as all alike were daughters of the Amorite and Hittite.
