Leviticus 23:30-32

American Standard Version

³⁰ And whatsoever soul it be that doeth any manner of work in that same day, that soul will I destroy from among his people. ³¹ Ye shall do no manner of work: it is a statute for ever throughout your generations in all your dwellings. ³² It shall be unto you a sabbath of solemn rest, and ye shall afflict your souls: in the ninth day of the month at even, from even unto even, shall ye keep your sabbath.
