"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
