Leviticus 23:28-30

Young's Literal Translation

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.

²⁹ `For any person who is not humbled in this self-same day hath even been cut off from his people;

³⁰ and any person who doth any work in this self-same day I have even destroyed that person from the midst of his people;
