John Gill, on Ezek 16:55

For thy sister Sodom was not mentioned by thy mouth,.... Or, "was not for a hearing", or "a report, in thy mouth" (g); the destruction of Sodom, though it was such an awful judgment of God, so flagrant and notorious, was visible and just at hand; yet it was not taken notice of, nor talked of; it was not the subject of conversation among friends; it was not reported from father to son, or heard of the one by the other; it was not regarded, nor was warning taken by it, which might have been, had it been more frequently mentioned; but they did not care, or neglected to speak of it; though it was "an ensample to those that should after live ungodly", Pe2 2:6; yet it was not for instruction to them, as the Targum paraphrases it; they learned nothing by it; or Sodom was so infamous for sin and punishment, that they scorned to make mention of its name; and yet they were as great Or greater sinners, and deserving of sorer punishment: in the day of thy pride; or "prides", or "excellencies" (h); in the time of their prosperity, in the days of David and Solomon, and other kings of Judah. Prosperity is apt to make men proud, and to lift them above themselves; and to forget what they have been, and what they may be; and to neglect observing the judgments of God on others, and to take warning by them.
