Numbers 35:28 DBY

²⁶  But if the manslayer shall in any way come outside the limits of the city of his refuge whither he hath fled,

²⁷  and the avenger of blood find him outside the limits of his city of refuge, and the avenger of blood kill the manslayer, there shall be no blood-guiltiness upon him;

²⁸  for the manslayer should have remained in the city of his refuge until the death of the high-priest; but after the death of the high-priest he may return into the land of his possession.

²⁹  And this shall be unto you a statute of right throughout your generations in all your dwellings.

³⁰  Whoever shall smite a person mortally, at the mouth of witnesses shall the murderer be put to death; but one witness shall not testify against a person to cause him to die.
