Exodus 31:14-15

UKJV(i) 14 All of you shall keep the sabbath therefore; for it is holy unto you: every one that defiles it shall surely be put to death: for whosoever does any work therein, that soul shall be cut off from among his people. 15 Six days may work be done; but in the seventh is the sabbath of rest, holy to the LORD: whosoever does any work in the sabbath day, he shall surely be put to death.
