[Among] the cities which you give to the Levites shall be the six cities of refuge, which you shall provide for the one who commits manslaughter to flee to; and in addition to them you shall give forty-two cities [to the Levites].
Therefore there is now no condemnation [no guilty verdict, no punishment] for those who are in Christ Jesus [who believe in Him as personal Lord and Savior]. [John 3:18]
so that the person (manslayer) who kills any person unintentionally, without premeditation, may flee there, and they shall be your refuge from the blood avenger. [Num 35:10ff]
