Leviticus 23:27 Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an set apart convocation unto you; and you shall afflict your souls, and offer an offering made by fire unto YAHUAH28 And you shall do no work in that same day: for it is a day of atonement, to make an atonement for you before YAHUAH your Elohiym29 For whatsoever soul it be that shall not be afflicted in that same day, he shall be cut off from among his people. 30 And whatsoever soul it be that doeth any work in that same day, the same soul will I destroy from among his people. 31 You shall do no manner of work: it shall be a statute for ever throughout your generations in all your dwellings. 32 It shall be unto you a shabbath of rest, and you shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.
Make sure that you AFFLICT (HUMBLE) your soul. Most people think fasting is the key but atonement is all about forgiving. You have to humble (afflict) your soul to forgive and also to ask for forgiveness. Yes it does HURT forgive according to the scripture. Once you forgive it can't be used again in judgment or condemning a person but so many people hold on to things in their heart. Do yourself a favor and release the scapegoat.
Happy Atonement mishpakah.
