Êxodo 21:36

36 Mas, se for notório que o boi já antes costumava chifrar, e o seu dono não o prendeu, certamente pagará boi por boi; porém o boi morto será seu.

36 However, if it was known that the bull had the habit of goring, yet the owner did not keep it penned up, the owner must pay, animal for animal, and take the dead animal in exchange.
