Was not your sister Sodom a byword in your mouth in the day of your pride,
God here blames the Jews because they did not attend to that remarkable judgment which he had executed against the Sodomites: for they had always before their eyes what ought to retain them in the fear of God; for that was a formidable spectacle, as it is this day. They knew that region to have been like the paradise of God, as it is called by Moses.
The prophet here further shows Jerusalem her abominations, by comparing her with those places that had gone before her, and showing that she was worse than any of them, and therefore should, like them, be utterly and irreparably ruined. We are all apt to judge of ourselves by comparison, and to imagine that we are sufficiently good if we are but as good as such...
Commenting on Ezekiel 16:44-59
Before thy wickedness was discovered,.... By the punishment of it, by the judgments of God brought upon them; then they were humbled, who before were proud and haughty; and might speak and think of the vengeance of God on Sodom, which before they made no mention of.
