Numbers 35:30-32

Common English Bible

³⁰ Anyone who kills another will be executed on the evidence of witnesses. But one witness alone cannot testify against a person for a death sentence. ³¹ You may not accept a ransom for the life of a killer, who is guilty of a capital crime, for he must definitely be put to death. ³² You may not accept a ransom for someone who has fled to his refuge city so that he can return and live in the land before the priest’s death.
