اَلْعَدَد 35:33

لَا تُدَنِّسُوا ٱلْأَرْضَ ٱلَّتِي أَنْتُمْ فِيهَا، لِأَنَّ ٱلدَّمَ يُدَنِّسُ ٱلْأَرْضَ. وَعَنِ ٱلْأَرْضِ لَا يُكَفَّرُ لِأَجْلِ ٱلدَّمِ ٱلَّذِي سُفِكَ فِيهَا، إِلَا بِدَمِ سَافِكِهِ.

So ye shall not pollute the land wherein ye are: for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it.
