Now viewing scripture range from the book of Numbers chapter 35:28 through chapter 35:31...
28 Because he should have remained in the city of his refuge until the death of the high priest: but after the death of the high priest the slayer shall return into the land of his possession.
29 So these things shall be for a statute of judgment unto you throughout your generations in all your dwellings.
30 Whoso killeth any person, the murderer shall be put to death by the mouth of witnesses: but one witness shall not testify against any person to cause him to die.
31 Moreover ye shall take no satisfaction for the life of a murderer, which is guilty of death: but he shall be surely put to death.
