Exodus 31:14

You shall keep the Sabbath , because it is holy for you. Everyone who profanes it shall be put to death . Whoever does any work on it, that soul shall be cut off from among his people .

“‘Observe the Sabbath, because it is holy to you. Anyone who desecrates it is to be put to death; those who do any work on that day must be cut off from their people.

Ye shall keep the sabbath therefore; for it is holy unto you: every one that defileth it shall surely be put to death : for whosoever doeth any work therein, that soul shall be cut off from among his people.
