Leviticus 23:26 YLT

²⁴  'Speak unto the sons of Israel, saying, In the seventh month, on the first of the month, ye have a sabbath, a memorial of shouting, a holy convocation;

²⁵  ye do no servile work, and ye have brought near a fire-offering to Jehovah.'

²⁶  And Jehovah speaketh unto Moses, saying,

²⁷  'Only -- on the tenth of this seventh month is a day of atonements; ye have a holy convocation, and ye have humbled yourselves, and have brought near a fire-offering to Jehovah;

²⁸  and ye do no work in this self-same day, for it is a day of atonements, to make atonement for you, before Jehovah your God.
