اَلْعَدَد 35:21

أَوْ ضَرَبَهُ بِيَدِهِ بِعَدَاوَةٍ فَمَاتَ، فَإِنَّهُ يُقْتَلُ ٱلضَّارِبُ لِأَنَّهُ قَاتِلٌ. وَلِيُّ ٱلدَّمِ يَقْتُلُ ٱلْقَاتِلَ حِينَ يُصَادِفُهُ.

Or in enmity smite him with his hand, that he die: he that smote him shall surely be put to death; for he is a murderer: the revenger of blood shall slay the murderer, when he meeteth him.
