Proverbs 30:33 in the World English Bible
For as the churning of milk produces butter, and the wringing of the nose produces blood, so the forcing of wrath produces strife.”
Context
32 If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thine hand upon thy mouth.
33 Surely the churning of milk bringeth forth butter, and the wringing of the nose bringeth forth blood: so the forcing of wrath bringeth forth strife.
