Matthew Poole and continuators on Proverbs 30:32

32 If thou hast done foolishly in lifting up thy self , or if thou hast thought evil , lay thine hand upon thy mouth .

Either 1. By Rebellion or Sedition against the King last mentioned. Or 2. By Anger or Wrath, of which he speaks in the next verse. But this Verse hath no necessary dependance either upon the foregoing or following Verse. Or 3. Through thy Pride, which makes men carry themselves very foolishly, and scornfully, and injuriously, and is the root of contention, as was observed, Prov. 13. 10.

i. e. Designed any mischief or injury against thy Neighbour.

To wit, to shut it: Be silent, as this Phrase is used, Iob 21. 5. & 29. 9. Restrain thy self, do not speak one word, much less do any thing tending to the accomplishment of it: Do not open thy mouth to justifie or excuse it, but silently and seriously consider the evil of it, and repent of it, and do so no more.
