Leviticus 23:28-30

Christian Standard Bible

²⁸ On this particular day you are not to do any work, for it is a Day of Atonement to make atonement for yourselves before the Lord your God. ²⁹ If any person does not practice self-denial on this particular day, he is to be cut off from his people. ³⁰ I will destroy among his people anyone who does any work on this same day.
