Exodus 31:14

“Ye shall keep the sabbath therefore, etc.] Strictly observe it, according to the rules given concerning it: for it is holy unto you; a day that was set apart of God for holy exercises, peculiarly on their account: everyone that defileth it; by doing any servile work upon it, or not observing it in a religious way; shall surely be put to death; by the hand of the civil magistrate; if the law of the Jewish sabbath is now in force, the sanction continues, and the violation of it ought to be punished by a judge with death: for whosoever doeth any work therein; so much as to kindle a fire, and dress any food, by boiling or roasting, or any other way: that soul shall be cut off from among his…”

This is not to say that followers of God must always punish those who commit these offenses in this way; but here at the outset, it was vital to make this truth clear (see Acts 5:1-11). If the spiritual truth of this lesson has not been learned, mere ritual obedience will be of no value (see Col 2:16-19).”
