Deuteronomy 19

Cities of Refuge

19:1 When the LORD thy God hath cut off the nations, whose land the LORD thy God giveth thee, and thou succeedest them, and dwellest in their cities, and in their houses;

19:2 Thou shalt separate three cities for thee in the midst of thy land, which the LORD thy God giveth thee to possess it.

19:3 Thou shalt prepare thee a way, and divide the coasts of thy land, which the LORD thy God giveth thee to inherit, into three parts, that every slayer may flee thither.

19:4 And this is the case of the slayer, which shall flee thither, that he may live: Whoso killeth his neighbour ignorantly, whom he hated not in time past;

19:5 As when a man goeth into the wood with his neighbour to hew wood, and his hand fetcheth a stroke with the axe to cut down the tree, and the head slippeth from the helve, and lighteth upon his neighbour, that he die; he shall flee unto one of those cities, and live:

19:6 Lest the avenger of the blood pursue the slayer, while his heart is hot, and overtake him, because the way is long, and slay him; whereas he was not worthy of death, inasmuch as he hated him not in time past.

19:7 Wherefore I command thee, saying, Thou shalt separate three cities for thee.

19:8 And if the LORD thy God enlarge thy coast, as he hath sworn unto thy fathers, and give thee all the land which he promised to give unto thy fathers;

19:9 If thou shalt keep all these commandments to do them, which I command thee this day, to love the LORD thy God, and to walk ever in his ways; then shalt thou add three cities more for thee, beside these three:

19:10 That innocent blood be not shed in thy land, which the LORD thy God giveth thee for an inheritance, and so blood be upon thee.

(19:5-6) He shall flee unto one of those cities ... Lest the avenger of the blood ... slay him.

If a person kills someone unintentionally then he or she can flee to a city of refuge to escape being killed by the "revenger of blood."
I guess this is (sort of) good--about as good as it gets in the Bible anyway. But it would be better to declare such a person innocent, assuming no criminal negligence involved, rather than creating a city for the person to flee to. And the idea of a "revenger of blood" is just plain creepy.

The Avenger of Blood
19:11-13

19:11 But if any man hate his neighbour, and lie in wait for him, and rise up against him, and smite him mortally that he die, and fleeth into one of these cities:

(19:11-13) A murderer is to be killed by "the avenger of blood" and "thine eye shall not pity him."

19:12 Then the elders of his city shall send and fetch him thence, and deliver him into the hand of the avenger of blood, that he may die.

(19:12) The elders of his city shall send and fetch him thence, and deliver him into the hand of The avenger of blood, , that he may die.

19:13 Thine eye shall not pity him, but thou shalt put away the guilt of innocent blood from Israel, that it may go well with thee.

(19:13) Thine eye shall not pity him.

Landmarks and Witnesses
19:14-21

19:14 Thou shalt not remove thy neighbour's landmark, which they of old time have set in thine inheritance, which thou shalt inherit in the land that the LORD thy God giveth thee to possess it.

(19:14)

19:15 One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.

19:16 If a false witness rise up against any man to testify against him that which is wrong;

19:17 Then both the men, between whom the controversy is, shall stand before the LORD, before the priests and the judges, which shall be in those days;

(19:15) At the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.
Jehovah's Witnesses and the Two Witness Rule

19:18 And the judges shall make diligent inquisition: and, behold, if the witness be a false witness, and hath testified falsely against his brother;

19:19 Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put the evil away from among you.

(19:18-19) If the witness be a false witness ... then shall ye do unto him, as he had thought to have done unto his brother.

Do unto false witnesses as the criminals intended to do to their victims.

19:20 And those which remain shall hear, and fear, and shall henceforth commit no more any such evil among you.

19:21 And thine eye shall not pity; but life shall go for life, eye for eye, tooth for tooth, hand for hand, foot for foot.

(19:21) And thine eye shall not pity. Life for life, eye for eye, tooth for tooth, hand for hand, foot for foot.
