Numbers Chapter 35 American Standard-ASV1901
Command the children of Israel, that they give unto the Levites of the inheritance of their possession cities to dwell in; and suburbs for the cities round about them shall ye give unto the Levites.
And ye shall measure without the city for the east side two thousand cubits, and for the south side two thousand cubits, and for the west side two thousand cubits, and for the north side two thousand cubits, the city being in the midst. This shall be to them the suburbs of the cities.
And the cities which ye shall give unto the Levites, they shall be the six cities of refuge, which ye shall give for the manslayer to flee unto: and besides them ye shall give forty and two cities.
And concerning the cities which ye shall give of the possession of the children of Israel, from the many ye shall take many; and from the few ye shall take few: every one according to his inheritance which he inheriteth shall give of his cities unto the Levites.
For the children of Israel, and for the stranger and for the sojourner among them, shall these six cities be for refuge; that every one that killeth any person unwittingly may flee thither.
or in enmity smote him with his hand, so that he died; he that smote him shall surely be put to death; he is a murderer: the avenger of blood shall put the murderer to death, when he meeteth him.
and the congregation shall deliver the manslayer out of the hand of the avenger of blood, and the congregation shall restore him to his city of refuge, whither he was fled: and he shall dwell therein until the death of the high priest, who was anointed with the holy oil.
because he should have remained in his city of refuge until the death of the high priest: but after the death of the high priest the manslayer shall return into the land of his possession.
So ye shall not pollute the land wherein ye are: for blood, it polluteth the land; and no expiation can be made for the land for the blood that is shed therein, but by the blood of him that shed it.
