Numbers 35:31-33

Revised Geneva Translation

³¹ ‘Moreover, you shall take no ransom for the life of the murderer who is worthy to die. But he shall be put to death.

³² ‘Also, you shall take no ransom for he who has fled to the city of his refuge, so that he should return and dwell in the land before the death of the High Priest.

³³ ‘So you shall not pollute the land in which you shall dwell. For blood defiles the land. And the land can only be cleansed of the blood that is shed upon it but by the blood of he who shed it.
