A vara é para as costas do falto de entendimento (A rod is for the back of him that is void of understanding)

 Nos lábios do sábio se acha a sabedoria,

mas a vara é para as costas do falto de entendimento. 

Provérbios 10:13

In the lips of him that hath understanding wisdom is found:   
but a rod is for the back of him that is void of understanding. 

Proverbs 10:13
