Numbers 35:24-34

24the assembly must judge between the accused and the avenger of blood according to these regulations.

25The assembly must protect the one accused of murder from the avenger of blood and send the accused back to the city of refuge to which they fled. The accused must stay there until the death of the high priest, who was anointed with the holy oil. 26“ ‘But if the accused ever goes outside the limits of the city of refuge to which they fled 27and the avenger of blood finds them outside the city, the avenger of blood may kill the accused without being guilty of murder.

28The accused must stay in the city of refuge until the death of the high priest; only after the death of the high priest may they return to their own property.

29“ ‘This is to have the force of law for you throughout the generations to come, wherever you live.

30“ ‘Anyone who kills a person is to be put to death as a murderer only on the testimony of witnesses. But no one is to be put to death on the testimony of only one witness.

31“ ‘Do not accept a ransom for the life of a murderer, who deserves to die. They are to be put to death.

32“ ‘Do not accept a ransom for anyone who has fled to a city of refuge and so allow them to go back and live on their own land before the death of the high priest. 33“ ‘Do not pollute the land where you are. Bloodshed pollutes the land, and atonement cannot be made for the land on which blood has been shed, except by the blood of the one who shed it. 34Do not defile the land where you live and where I dwell, for I, the LORD, dwell among the Israelites.’ ”
