The Book of Deuteronomy is the fifth book of the Torah (Pentateuch) and is recognized as canonical by all major Christian traditions and by Judaism. The English title derives from the Greek 'Deuteronomion', meaning 'second law', reflecting the reaffirmation and expansion of the law given at Sinai. The Hebrew name 'Devarim' means 'words'. The book consists of three discourses by Moses to the children of Israel in the plains of Moab, before they entered the Promised Land, reviewing the history of the desert wandering and reiterating the covenant with God.
Deuteronomy
Chapter 19
When the LORD your God cuts off the nations whose land the LORD your God gives you, and you succeed them and dwell in their cities and in their houses,
you shall set apart three cities for yourselves in the middle of your land which the LORD your God gives you to possess.
You shall prepare the way, and divide the borders of your land which the LORD your God causes you to inherit into three parts, that every man slayer may flee there.
This is the case of the man slayer who shall flee there and live: Whoever kills his neighbor unintentionally, and didn't hate him in the past—
as when a man goes into the forest with his neighbor to cut wood, and his hand swings the axe to cut down the tree, and the head slips from the handle and hits his neighbor so that he dies—he shall flee to one of these cities and live.
Otherwise the avenger of blood might pursue the man slayer while hot anger is in his heart, and overtake him, because the way is long, and strike him mortally, even though he was not worthy of death, because he didn't hate him in the past.
Therefore I command you to set apart three cities for yourselves.
If the LORD your God enlarges your border, as he has sworn to your fathers, and gives you all the land which he promised to give to your fathers;
and if you keep all this commandment to do it, which I command you today, to love the LORD your God, and to walk ever in his ways, then you shall add three cities more for yourselves, besides these three;
that innocent blood not be shed in the middle of your land which the LORD your God gives you for an inheritance, and so blood be on you.
But if any man hates his neighbor, lies in wait for him, rises up against him, strikes him mortally so that he dies, and he flees into one of these cities;
then the elders of his city shall send and bring him there, and deliver him into the hand of the avenger of blood, that he may die.
Your eye shall not pity him, but you shall purge the innocent blood from Israel, that it may go well with you.
You shall not remove your neighbor's landmark, which they of old time have set, in your inheritance which you shall inherit in the land that the LORD your God gives you to possess.
One witness shall not rise up against a man for any iniquity, or for any sin that he sins. At the mouth of two witnesses, or at the mouth of three witnesses, shall a matter be established.
If an unrighteous witness rises up against any man to testify against him of wrongdoing,
then both the men, between whom the controversy is, shall stand before the LORD, before the priests and the judges who shall be in those days;
and the judges shall make diligent inquisition; and behold, if the witness is a false witness, and has testified falsely against his brother,
then you shall do to him as he had thought to do to his brother. So you shall remove the evil from among you.
Those who remain shall hear, and fear, and will never again commit any such evil among you.
Your eyes shall not pity: life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
