Leviticus 23:30-32

Amplified Bible

³⁰ If there is any person who does any work on this same day, I will destroy that person from among his people. ³¹ You shall do no work at all [on that day]. It is a permanent statute throughout your generations wherever you may be. ³² It is to be to you a Sabbath of complete rest, and you shall humble yourselves. On the ninth day of the month at evening, from evening to evening you shall keep your Sabbath.”
