Exodus 21:36

Or if it is known that the ox has been accustomed to gore in the past , and its owner has not kept it in , he shall repay ox for ox , and the dead beast shall be his.

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.

Or if it be known that the ox hath used to push in time past, and his owner hath not kept him in; he shall surely pay ox for ox; and the dead shall be his own. Exodus 20 Books Exodus 22
