Leviticus 23:30

And whatsoever soul [it be] that doeth any work in that same
day
Any sort of work whatever; for, as before observed, it was to be kept as strictly as the weekly sabbath:

the same soul will I destroy from among his people;
with the pestilence, as the above Targum; it seems to be but another phrase for cutting them off, and to signify the same thing.
