Numbers 35:23-25

New Catholic Bible

²³ or he has a deadly stone object and he does not see the other, but drops it on him causing him to die, and he was not an enemy nor was he seeking to harm the other person, ²⁴ then the assembly will judge between the killer and the kinsman avenger of blood according to these ordinances: ²⁵ the assembly will save the killer from the hands of the kinsman avenger of blood. The assembly will send him back to the city of refuge to which he fled. He will live in it until the death of the high priest who was anointed with holy oil.
