Numbers 35:31-32
31 You are not to accept a ransom for the life of a murderer who is guilty of killing someone; he must be put to death.
32 Neither should you accept a ransom for the person who flees to his city of refuge, allowing him to return and live in the land before the death of the high priest.(a)
