Proverbs 30:31-33 New Revised Standard Version Catholic Edition (NRSVCE)
31 the strutting rooster, the he-goat,
and a king striding before his people.
32 If you have been foolish, exalting yourself,
or if you have been devising evil,
put your hand on your mouth.
33 For as pressing milk produces curds,
and pressing the nose produces blood,
so pressing anger produces strife.
