Leviticus 23:30-32

New Century Version

³⁰ If anyone works on this day, I will destroy that person from among the people. ³¹ You must not do any work at all; this law will continue for people from now on wherever you live. ³² It will be a special day of rest for you, and you must deny yourselves. You will start this special day of rest on the evening after the ninth day of the month, and it will continue from that evening until the next evening.”
