Effects of wrath
If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thine hand upon thy mouth. 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. (Proverbs 30:32-33)
Other reference in Proverbs about wrath is given below:
An angry man stirs up dissension, and a hot-tempered man abounds in transgression. (Proverbs 29:22).
The irritation and provocation of anger occasion quarrels and contentions. Consequences of anger are severe as the churning of milk and the wringing of the nose.
Do not lose your temper at any cost, though you are provoked.
