1And the LORD spake unto Moses after the death of the two sons of Aaron, when they offered before the LORD, and died;34And this shall be an everlasting statute unto you, to make an atonement for the children of Israel for all their sins once a year. And he did as the LORD commanded Moses.

26And the LORD spake unto Moses, saying,27Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the LORD.28And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the LORD your God.29For whatsoever soul it be that shall not be afflicted in that same day, he shall be cut off from among his people.30And whatsoever soul it be that doeth any work in that same day, the same soul will I destroy from among his people.31Ye shall do no manner of work: it shall be a statute for ever throughout your generations in all your dwellings.32It shall be unto you a sabbath of rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye celebrate your sabbath.
