Exodus 21:33-36

And if a man shall open a pit, or if a man shall dig a pit, and not cover it, and an ox or an ass fall therein; the owner of the pit shall make it good, and give money unto the owner of them; and the dead beast shall be his. And if one man's ox hurt another's, that he die; then they shall sell the live ox, and divide the money of it; and the dead ox also they shall divide. 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.
