All his anger, doth a dullard let go, but, a wise man, by keeping it back, stilleth it.

El necio da suelta á todo su espíritu; mas el sabio al fin le sosiega.

A fool uttereth all his mind: but a wise man keepeth it in till afterwards.

A fool vents all of his anger, but a wise man brings himself under control.
