"This shall be a statute forever for you:  
    In the seventh month,
    on the tenth day of the month,
        you shall afflict your souls,
        and do no work at all,
            whether a native of your own country
            or a stranger who dwells among you. 

On that day the priest shall make atonement for you, 
    to cleanse you,
    that you may be clean from all your sins 
            before the Lord. 

This shall be an everlasting statue for you,
to make atonement for the children of Israel, 
    for all their sins,
        once a year."

                                                                     ---Leviticus 16:29-34
