اَلتَّثْنِيَة 19:6

لِئَلَّا يَسْعَى وَلِيُّ ٱلدَّمِ وَرَاءَ ٱلْقَاتِلِ حِينَ يَحْمَى قَلْبُهُ، وَيُدْرِكَهُ إِذَا طَالَ ٱلطَّرِيقُ وَيَقْتُلَهُ، وَلَيْسَ عَلَيْهِ حُكْمُ ٱلْمَوْتِ، لِأَنَّهُ غَيْرُ مُبْغِضٍ لَهُ مُنْذُ أَمْسِ وَمَا قَبْلَهُ.

Lest the avenger of the blood pursue the slayer, while his heart is hot, and overtake him, because the way is long, and slay him; whereas he was not worthy of death, inasmuch as he hated him not in time past.
