'Guilty' in the Bible

"Speak to the {Israelites}: 'When a man or woman {commits} any of the sins of humankind by acting unfaithfully, [it is] a sin against Yahweh, and that person will be guilty;

and the blood avenger finds him outside the territory of the city of his refuge, and the blood avenger kills the killer, {he will not be guilty of blood}

Also, you will not take a ransom payment for the life of a killer who [is] guilty of death; indeed, he must surely be put to death.
