Êxodo 21:36

36 Mas, se for notório que o boi era já, dantes, chifrador, e o seu dono não o prendeu, certamente, pagará boi por boi; porém o 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.
