他们可以住在那里直到大祭司死去，大祭司的死亡象征着净化，或移除这个意外杀人者的罪孽或不洁。

Show him no pity. You must purge from Israel the guilt of shedding innocent blood, so that it may go well with you.
你眼不可顾惜他，却要从以色列中除掉流无辜血的罪，使你可以得福。

The priest is to take some of the blood of the guilt offering and put it on the lobe of the right ear of the one to be cleansed, on the thumb of his right hand and on the big toe of his right foot.
