Numbers 35:30-32

Darby Translation

³⁰ Whoever shall smite a person mortally, at the mouth of witnesses shall the murderer be put to death; but one witness shall not testify against a person to cause him to die.

³¹ And ye shall take no satisfaction for the life of a murderer, who is guilty of death, but he shall certainly be put to death.

³² And ye shall take no satisfaction for him that hath fled to the city of his refuge, that he should come again to dwell in the land, until the death of the priest.
