9 because you carefully follow all these laws I command you today—to love the LORD your God and to walk always in obedience to him—then you are to set aside three more cities.
10 Do this so that innocent blood will not be shed in your land, which the LORD your God is giving you as your inheritance, and so that you will not be guilty of bloodshed.
11 But if out of hate someone lies in wait, assaults and kills a neighbor, and then flees to one of these cities,
12 the killer shall be sent for by the town elders, be brought back from the city, and be handed over to the avenger of blood to die.
13 Show no pity. You must purge from Israel the guilt of shedding innocent blood, so that it may go well with you.
14 Do not move your neighbor’s boundary stone set up by your predecessors in the inheritance you receive in the land the LORD your God is giving you to possess.

Witnesses

15 One witness is not enough to convict anyone accused of any crime or offense they may have committed. A matter must be established by the testimony of two or three witnesses.
16 If a malicious witness takes the stand to accuse someone of a crime,
17 the two people involved in the dispute must stand in the presence of the LORD before the priests and the judges who are in office at the time.
18 The judges must make a thorough investigation, and if the witness proves to be a liar, giving false testimony against a fellow Israelite,
19 then do to the false witness as that witness intended to do to the other party. You must purge the evil from among you.
