Leviticus 23:30-32

Darby Translation

³⁰ And every soul that doeth any manner of work on that same day, the same soul will I destroy from among his people.

³¹ No manner of work shall ye do: [it is] an everlasting statute throughout your generations in all your dwellings.

³² A sabbath of rest shall it be unto you; and ye shall afflict your souls. On the ninth of the month at even, from even unto even, shall ye celebrate your sabbath.
