Orthodox Jewish Bible

²⁹ For whatsoever nefesh it be that shall not be afflicted in that same day, he shall be cut off from among his people.

³⁰ And whatsoever nefesh it be that doeth any work in that same day, that nefesh will I destroy from among his people.

³¹ Ye shall do no manner of work; it shall be a chukkat olam throughout your dorot in all your dwellings.
